The full benefits of the cold air intake or long tube headers can only be achieved through a tune although it's not absolutely necessary. Would purchase/install the headers now and cold air intake later....I'm also looking for some either some LTH's or a CAI/OTR intake. Wife has informed me I can only chose one right now, which should I do first? I would assume exhaust first would result in more noticeable gain over the intake.
Close to mine (and the one PatG spec'd). I'm all for doing a converter eventually but for now, I've just dropped some significant coin on the DOD delete and cam. Kinda annoying how much extra work has to be done just to get rid of DOD when replacing the cam should be a cheap and quick job.You're probably still going to want to put a stall converter in. I just did a DOD delete with a PatG custom spec cam over the winter and I still push the brakes quite a bit. It isn't bad but I'm planning to put a converter in once the snow goes away. My cam specs are 222/226 .600"/.600" 112 LSA.
Appreciate the input. I'm not against remote tuning and it may be an option later down the road. I think for now I'm doing the local shop and later I'll probably end up either buying the hptuners or borrowing one from a friend who Is also considering buying it. I'm also not completely against changing the converter i would just prefer not to do it in my tiny 2 car garage. I'm more than capable enough to do it I and I probably will in the future. Either way, the car isn't daily driven so it will only be annoying to drive on weekends the cam pushing the brakes also gives me a reason to upgrade the fronts to brembos.I would not recommend the BTR stage 2 with stock converter. I had it with ZL1 converter and was not a big fan. Would only be worse with stock. CAN it be done yes, but your tune is going to have to be absolutely perfect, which is going to require someone familiar with G8's not just "LS and 6L80".
Aside from tuning issues, pushing on the brakes, etc... the BTR stage 2 feels like a pig at low RPM. It starts to breathe ~3500 rpm, so it's really best suited with a matching converter.
I remote tune my car. It's simple and as good or better than local since you can get someone familiar with G8s. For my current build I'm remote tuning during a dyno session. See if there's a shop near you that has experience doing that. At that point it's just like having your tuner in the seat next to you.
