Tom, since you are going to US41 with me on the 30th, we should have time to work on the launch, tire pressure issue here before we leave...I won't guess as to the problem until I see you and the engine. If not leaks, everything installed to specs, then I would guess a tune problem, which the guys at the track can help you with...but had you and I not played at the Dragon, my guess is launch, tire pressure right now...car was sounding and feeling good...just got to let her rip...burn those tires baby....question for Rob...did you see his rpms per gear....was he above 6K????
