well my last gtp ran 10.2... the cartuning performance grand prix runs 8's... but thats stripped down... im not lookin to break 9's or 8's just 10's really.. anything less becomes too unstreetable. 10.2 wasnt easy to get but is possible, and the great thing about our performance shift button is you can electronically limit the car to reasonable power for the street, then killer power for the track when you push it. 2 completely different animals at the push of a button. all in all about 15-17k is gonna go into this car over time. it wont be my daily driver when its done. itll be more of a toy at that point.
