Only word of advice I give ya is, keep the kit at 75 shot! On a boosted, motor nitrous works very well and you get more gain then on a N/A motor. Unless you want to put a window in your block that is. If Jon is tuning your car, 10 to 1 he will tell you to run a dry kit and he will tune for the extra fuel. Other than that there is really nothing out of the norm to add a kit to these cars, the black out kit from Zex is a common one that a few of the other GT500 owners that I know run.
