Canned Tune Vs. Personal Tune
Hey all, I have a couple questions to ask as a new G8 GT owner. I have read through many threads regarding tunes on the G8. I realize they are pretty detuned from the factory; pretty obvious when they are "okay" to run 87 octane.
Now prior to the G8 GT I had a Grand Prix GXP (5.3 LS4) and had it tuned through someone in downstate Michigan. I met him through the forums and he is VERY VERY educated on tuning. Im not! Now what I remember from when he did my tune he worked with the VE tables and a lot of torque management and MAF numbers. I cant tell he what he did exactly (because I dont know!) but hed did spend the good part of 2-3 hours tuning the car. We did a few road runs to get numbers and we would go back in to change some things around. His cost on this was $250 being I was a fellow board member.
Now, I have seen a few Cortex tuners going for sale and the main advantage I see with these is that I could swap tunes whenever I feel the need. I.e roadtrip vs track.
1. Do you think I will gain more with a personal tune vs the canned tunes from the Cortex?
2. If I get a CAI and Exhaust how does the cortex respond? Or does SC have a package for me?
3. Has anyone had problems with the Cortex bricking there cars? The reason I ask is because I had a Diablosport Trinity before the tune on my GXP and it bricked my car. Obviously, Diablosport DIDNT help and left me with all expenses.
Thanks for the help and happy G8'ing
