I was wondering where is a good place to start with this vehicle. I installed the stock Magnacharger kit 2 years ago and it has been running fine ever since. The customer was thinking about a new ZL1 camaro but I said lets up the boost a bit and get the Magnuson tune out of there. Went to a 3.6" pulley (~8psi) and have the car tuned on my mustang chassis dyno. The transmission tune has always been stock and 6 spd automatic transmission tuning is one of my weak spots. I would like to learn more and improve my knowledge of the 6L transmissions. Would the bone stock 2010 CTS-V be a good start or should I copy over the values from the G8 mod file in the Tuning Files directory.
Thanks
