Turbomom ran a new best in the 06 gt 12.98, and the best mph was a 105.63 mph. The mod's are as listed 4:10's, Dragradials, C&L street intake, and predator 93 octane tune. We have not stripped any weight out of the car or removed the sway bar. Next mod will be under drive pulley's. Then after we see what that does I'm going to put a converter in it. Gregg
