Before the mods shut this one down too. It's my car he is talking about and it's all true.

I'll just paste this from a conversation earlier today that triggered this.

"I'm glad to be part of the tight knit muscle car community. I recently had work done by a performance shop and they messed up everything they touched. and screwed me out of a lot of money. It took a while for it to sink in but friends of mine spread the word at the race track and in the online muscle car community. I've received countless private messages and emails from people willing to help solve the problems. Other car guys, shops, friends, and even an attorney(Thought they where all snakes, maybe I was wrong). Some who have had very similar experiences with the same tuner costing them lots of money.

I'm always the one helping friends when they get screwed over by mechanics and I fix friends cars for free. I never thought it would happen to me. They couldn't fix the problems that they admitted to, and made some worse. Denied other problems and even slandered myself and 2 friends who's cars they also messed up in the process. My car still isn't right. Having someone else tune it for more money. Not sure what to do. I've taken the car back 4 times and got nowhere. Do I just keep paying other places to fix it? Go to all the forums with my story and proof? BBB claims? Consumer affairs? Court? Wish they would just make it right. But I've given them too many opportunities which involved me missing work and renting cars. wtf"

Got air in the ABS module because they left the calipers off and didn't cap the lines requiring dealer purge(out of my pocket), installed rear brake calipers on the wrong side(upside down), Put the CAI on wrong over the rad support and shut the hood on it now the hood is tweaked, mangled the Borla X-pipe connecting it to the headers. One side knocked the transmission mount, the other side was entirely below the frame and hit the ground everywhere. Wrong clamps that leak. 2 different clamps on each side for the Non stainless adapters. Entire exhaust was out of place. Tips where googly-eyed with one side touching the plastic. Cost me over $300 for custom exhaust work to fix it. Over filled the transmission. 60 more RWHP and 3200 stall and went slower at the track. Tune was so messed up I'll only type a little of it. The converter locked and unlocked erratically, Down shifted hard enough to chirp tires, some upshifts where laggy, and some hard as hell, turned off all Evap related parameters. A 6L80E calibrator replied to my email with "who the f*@k tuned this"? ... Strut mounts fell apart when they put the drop springs on. Bearing rolled on the floor. But didn't tell me till after I picked the car up. And charged me $115 for a "performance" alignment. Just found out today that they have had my wheels back from the paint shop for a week and still haven't called.

Your the one helping friends fix their cars for free but you pay a shop to install headers? Seems odd..

Didnt Powerhaus refund your money for the tune and flash it back to what you came in the door with? Sometimes its worth firing a customer...

If the tune was so messed up why dont you post it up? I'll take a look at it and tell you what I think.

And I thought powerhaus was a respectable performance shop.....

They are, numerous friends and CCG8 members have gone to Powerhaus since they opened and received excellent service. Off the top of my head at least 6 members have gone there and have zero complaints. Countless cars, literally hundreds (probably thousands) of cars went to Powerhaus coowner/tuner previous shop... its not like he just started tuning, I've been going to him for years.

One of our club members car is there now. I'll have him post a review of their work once complete. He's having a dod delete cam swap done, fuel pump upgrade, and tune... he already had a maggie on the car.

 

This is ****ty. And I get why mods lock threads like these but damnit if it isn't good to see the community supporting itself by being vocal about those who would do harm.

Good luck man, hope it all gets worked out.

 

And I thought powerhaus was a respectable performance shop.....

 

I thought they were as well but ever since my buddies T/A got tuned there and ran like crap at the track, I have been hearing alot of negativity towards there shop and seeing it first hand on 4 different cars. IDK whats going on with them in recent. I would love to be able to take my car to thier shop since its so close to me but there is no way in hell I will let them touch any of my cars now. Hearing people bitch about them getting tuned there then blowing up there tranny in thier G8 or having a heads, cam, intake G8 dyno 388rwhp and a bolt on G8 making 379 on the same dyno after there tune? Does'nt make sense to me.

Why would you not call your customer and let them know that thier rims are finished and ready for pickup? Turns out the rims have been back @ powerhaus for a week now and mike just found out they were done yesterday by calling the paint shop because powerhaus would not return his calls?

 

I have seen some respectable guys on this forum defend this shop but this is just too much. Macko considering how much money you have tied up in this I might consider the attorney. If their tuner really is that uneducated with tuning they need to get him out of there before more cars get damaged. The fact that they accepted payment for all of this and then won't respond to your attempts to contact them is inexcusable. At this point I really don't care who vouches for this shop because they obviously have some issues. I mean what kind of shop manager would let something leave their shop with exhaust tips touching the diffuser. This sounds like another example of a shop building a good name at first and then getting overloaded with work and letting the quality drop off big time to try to keep up with the work load rather than expanding in the ways needed to handle the workload or simply letting potential customers know that they won't be able to start on their car immediately.

 

This is all what has happened. I was not trying to just talk crap on them. Mike has Pictures, Videos, Emails, everything after he got his car back from powerhaus and after he has fixed most of there work. The exhaust shop said it was crappy work, The people that checked out his tune said it was crappy tuning..

They put his broke strut mounts back in his car and aligned it. They charged him 115.00 for an alignment and told him he needs to get new strut mounts and get another alignment. Why did they not just call the customer to see if he wanted them to replace the Strut mounts since they were busted? They had the car for over 2 weeks doing headers, exhaust, stall, lower springs, and painted calibers, and pretty much everything was messed up.

 

Thats great that you have friends that have had good experiences with them. I have had friends that have not.

Mike has been trying to talk with them but they dont return his calls or emails.. The only reason he found out his rims were done is because he called the paint shop that painted them and they told him they were dropped off last week back at Powerhaus!

 

They emailed me the stock tune along with a 6th adjustment but did not respond to any other complaints or requests regarding refunds and I haven't received any correspondence since then. I have gone to the shop and noone was there. I have a pretty demanding career and can't be going out of my way any longer. They have had more than enough opportunities to make this right. I spoke highly of them even after my first problems. But Stopped when an owner blamed condition of my car and combination of parts. Those parts being listed above you can see that quality is not an issue. And an 2009 G8 with 35,000 miles that ran perfect with no problems except the strut mounts that are a known issue with our cars. What you said about them is why I went to them. He did my tune at RPM and it was flawless. Now not so much. We are going out of our way and dealing with stressful drama to warn others of these issues. Believe me.... I wish they did it right the first time...I'd still have Powerhaus in my signature and a sticker on my car. Now they will never touch my car again.

 

They tuned your car 5 times and couldnt get it correct? I did not know that.. Wow....

 

Uncko Macko didnt they also tune out your upstream o2 sensors and evap system!
For every one good review ive heard like 6 bad reviews.
Did you hve a thread on tech too? Should link this over there.

 

Did you guys stop by the shop when they were closed due to being in OCMD for hot rod/cruisin week? Pretty sure they posted up they would be closed during that time.

I'll take a look at the tune when I get home... dont have HPT on work computer.

 

No. We where in OCMD also. It was during normal business hours on 2 different days nowhere near OCMD or any other car show for that matter

 

Here is a video I shot of some of the problems during normal driving conditions.

Please see datalog file above to show that I am not playing with the throttle during the RPM bounce and Converter locking/unlocking.

Please see datalog file above to show that I am not playing with the throttle during the RPM bounce and Converter locking/unlocking.

Seems odd watching the video, its like your intentionally lugging the engine by running at low RPM in a high gear at low MPH with cruise control enabled. I'm not sure if your just on the verge of the converter locking and the throttle input from the ECM on cruise is causing it to unlock, granted I wouldnt want my converter locking at such low speeds but that could be stock settings. I can compare it to a stock tune later.

I would try it again at a higher MPH and see if it does the same thing, run at 70MPH in the high gear and do the same log in 5th gear. That will be a better indication.

 

Intentionally? I turned off the traction control, trans in Auto mode, and cruise control in 5 mph increments to show that it wasn't intentional because I was accused of that before. At the end of the video I do slightly open the throttle to show it is not locked when it should be. Please see the datalog file and tune to confirm. I am not guessing or giving an opinion...I am stating facts and showing proof.

 

I'm not saying your doing it intentionally with your foot... I'm saying the conditions that you setup are prone to failure. Change the conditions of your test at a higher MPH and RPM so your not lugging the engine and that will give a better result. If the converter still locks/unlocks cruising at 1,500, 2,000, 2,500 etc will prove your point rather then trying to lug around in 6th gear at 1,000RPM. I dont even drive my car in 6th under 60MPH and changed the tune to reflect that, car just feels like ass when you do that.

 

I rode in the car with him in ocmd even drove it alittle, it did it in every cruise situation regardless of gear rpm and mph. 98silverbird also rode in the car. Now that hes got the tune from the 6l80 calibrator he no longer has the issue.

 

Gotcha, so did you compare files to see what changed?

 

It was very anoying and Mike has shown very strong resistance in bitching about it. From riding in his car, and my wife actually driving his G8 if it were me I would have bitched about it as much as possible on every forum out there. When your just cruising about 50mph or faster,the Rpms just surge 500rpms up and then 500 rpms down the entire time!! my 3200 stalled Firebird never did that.. The whole 2 hr trip from NJ to OCMD with that surging would have driven me crazy. Riding in the car from Rehobath to OCMD was very anoying and I was the passenger. Between that surging and the exhaust hitting up underneath I would go crazy if it were my car..

So to sumerize with the tune from Powerhaus ( which was fine tuned 5 times) the car ran slower then it did before the parts and tune and acted like crap while driving around. Now Mike has a pretty much stock tune on the car and its faster then it was before he went to powerhaus and the drivability issues are resolved?

 

I'm not sure why you're giving me a hard time. Please look at the files that I have provided for your viewing pleasure.

Yes... I am intentionally showing all of you that the tune was doing some funky things.

It also did those things at highway speeds with steady throttle, cruise control, and even worse while decelerating. I wish I could have datalogged and had copies of the first couple tunes because they where worse.

I haven't even touched on track conditions. Shifts where super laggy. And I was unable to tap down and hold 3rd gear through the traps. It would upshift to 4th no matter what. The 3-4 shift was so laggy I might as well have gone through the traps in neutral. Now I have a base tune with minor settings for an aftermarket converter and ALL of these conditions have gone away.

I feel you man.. Your car is gonna fly once it gets a real tune on it! Bet you will be in the 12.4 range @ 113mph with a GOOD tune. Sucks that its has taken so long and cost so much money. I hope that the Powerhaus tune did not damage anything perminatly..

 

I have no problem with the guys at powerhaus. They recently tuned my friends 06 Jeep SRT8 and did a great job. Roshan's tune feels dead on and shifts smoothly. Negative publicity is typically outweighed greatly by the number of satisfied people who don't post up their experiences. Just my opinion..

 

The converter does what it is supposed to do now. Chris at Circle-D has been more than helpful in troubleshooting. Thanks Chris.

 

I bought a GXP that had work by a different 'Powerhouse' in Cicero NY, and you would be asstonished to find all the things worng with it. 2 Motor mounts missing nuts, 1 spark plug wire not seated, causing missing, and a PCM Tune by Speartech (PCM had been locked, but we got it unlocked) that looked to be a stock tune with a raised Idle to 900 RPM. There are other things, but it's disheartening to think about how many crappy shops are out there.

Here is what I have figured out. Person A is good and knows his ****, he gets busy, opens shop, does well. Person A hires person B, shop gets busier, shop hires person C. Person B & C are nothing special, it was Person A that was bad ass, but he's not working on your car...your car comes out like crap.

May you have better luck...
Charles

 

I hear ya. I'm not sure what happened. They where cool guys. They have done some bad a$$ cars. Roshan tuned mine the last time at RPM and I loved it. Everything they touched was messed up. I love this car and don't want to drive it anymore.

 

Why dont you want to drive it? I thought it drove fine and was faster now with the stock tune?

I compared the file you posted to about 5 of Roshans previous tunes on different cars... have to call it like I see it, that doesn't look like Roshans tuning at all.

 

It drives better than with Roshan's garbage tune by far. However it is a base tune and still needs work. The tuner I'm going to is really busy. After all the money I've spent at Powerhaus then all the money I've spent to have it done right...I don't want to look at the car anymore.

It's Roshan's tune. His 5th attempt at tuning my car. Here is a video of my car being tuned at powerhaus from the powerhaus youtube channel. You can see the botched exhaust job in the video.

It sucks not loving your can anymore because a shop ****ed up everything about it. Thats what happened to my friend with the T/A that got tuned there on N20. The tune sucked and it made it not fun anymore. Now he is in the market for another car. To gain only 3MPH from all motor to a 125 shot is just stupid. Now he has a damaged Tranny and he doesnt even want to deal with the car anymore because of how it runs after the tune.

 

We are here EVERYDAY from 9am-6pm. Often times way past 6pm...We are also here just about every Saturday. The only time we have been closed was for OCMD and it was posted. Also, I check the call log daily and have no calls from Mike! Incredible. No messages from him either! We sent him an email a few days ago to let him know that his wheels were done being powdercoated but still haven't heard back from him! Often times we would get 6-7 email responses from him a day but now he won't respond to any emails about coming to get his wheels?? Instead, we are being blamed for poor communication.


Again, I offered you a refund on your tune if you were unhappy with it. Instead, I was accused of not being confident in our work. Why didn't you come in for your refund? What gives?

Also, you KNEW about your strut bearings being bad. YOU TOLD US YOU TOOK IT TO THE DEALER FOR WARRANTY WORK BUT THEY DID NOT WANT TO HELP YOU. Why didn't you ask us to replace them????? Again, this is just being used to discredit our shop.

We have modified and tuned many cars since opening and you are the ONLY customer that has complained about all these issues we created. I find that overly odd. 1998silverbird has had some kinda of personal vendetta with us since day one. I don't know what his problem is. He has actually made up things that were completely untrue like the time he said a certain blue z06 had a huge dip in power after we tuned it. Newsflash, it had the huge dips when we baselined it! We also have never met him or dealt with him in person so I'm having a hard time trying to understand why he is talking **** about Powerhaus every chance he gets!

Here is a private message from 01slpss:


"Powerhaus Performance
We are just clearing the air with what your acquaintance is saying to bad mouth our shop when he has not had any first hand experience with us.
And as for reference you did bad mouth us publicly on facebook, which is your opinion you are entitled to. But Jeff was using your vehicle as a direct complaint against us that is the only reason your situation was brought up.

As for the 23* set across the timing table, I am not sure at what you were looking at because this is your timing table in the car when it left our shop. And we did pull extra timing in case you wanted to up the shot.

:screenshot of tune here:

May 9Kevin Garretson
well from here on out Im out of this. I do not know whats going on or why jeff is shooting his mouth off. I knew you and mike were trying really hard to figure out what was going on and jeff made it increasingly difficult. That timing table is nothing like what I saw when we pulled up the tune, so i dont know what had happened. Bottom line, Im out of this any future posts or anything that goes on Im not involved in, Ive told jeff to let it go several times already. I wish you guys the best."

Who is pulling the tunes from these cars? Is it the same person? Sounds like a possible conspiracy to me considering Roshan sent a screen shot of Kevin's car and it was nothing like what Kevin said he pulled from the car. Also, MGM GT has seen Roshans tunes in multiple cars and notes that the Red G8's tune is completely uncharacteristic of all the tunes he has seen. There has been DOZENS and DOZENS of happy G8 customers with custom tunes by Powerhaus. Hmmm...

 

I do not know why youre quoting me as 01slpss....i don't drive a Camaro.. That timing table you sent me was far from what was on my car. My car ran like **** on and off the spray. Idk how you can say there isn't something wrong when i only picked up 3mph on a 100 shot even AFTER i switched to a taller tire. My motor tune from rohan at rpm was excellent. Idk what changed. As for who this tuner who is pulling our tunes, he does not want to be involved. However he is extremely reputable and has many cars running incredible times. As for mike being the only unhappy customer you're clearly not paying attention because you have several. Maybe it's becausewe were the only ones to question your flawless tunes.. Or maybe since our cars are "rats nest" and in "poor condition" and according to you guys we're awful drivers who are "unsuitable to own performance cars" you guys really didn't care about us as much as your porches and lambos..i guess money talks even though mike spent a ton.

 

@ Mental

No one was there on May 22 at 12:19pm

I haven't called or emailed since May 23rd. Which means more than a month worth of time your business could have made the car right.

Everyone knows G8 strut mounts go bad. I knew it too. Couldn't get them done before vacation. However literally falling apart then putting them back on without calling me and then charging $115 for a "Performance" Alignment is absurd.

I have not received any emails from you or Roshan. Nothing in my spam folder either...Unless you're trying to sell me natural male enhancement.

My car has since been datalogged and the HPT files downloaded as I watched and I sent them to several Tuners and a calibrator is other states who do not know you so there is no bias. And it's been confirmed across the board that the tune was bad. Read Roshan's emails. It's all in there.

Complaints, while mine being more abundant than others...are defiantly not only coming from me. Open your eyes. There are several in this thread. And several more that have expressed similar sentiment at the track and meets that aren't on this forum. Maybe they'll pop up when this crosses to all the other forums. It FLEW around facebook. People on my facebook from the G8 community, musclecar community and my families professional drag racing friends read the comments about your shop and you trashing my car, parts, and one of your 20 yr old customers rats nest nitrous installs. It was bad, but come on man, wtf. People bring cars to you to make them better and learn something. You can't talk about your customers like that.
