I've tried posting logs and other data and have contacted every grand national person in my area and they are either too busy or will not answer the phone. I'm tired of waiting. I'm willing too drive 3 or 4 hours too a known good tuner. The car runs fine its just really slow. It may be as fast as its going too be with a stock engine and in that case I'm going too be very disappointed. I always heard how fast these cars are but I've never ridden in one other than my own so I don't have anything too compare it too. If anyone can help me out please send me a PM.
