Well track closes at the end of sept so time is running out. Last time out i trapped 107's and smoked the stock clutch. By the end of each run my clutch felt like butter and each shift got softer than the last. My goals are 109-110mph and ill be happy but who knows.
You can do a pretty good job on the street but will almost always benifit from fine tuning it on the dyno, the safety factor cannot be duplicated on the street and is a very big plus as well as consistant/comparable results.
