no the bike has plenty of power. i just want to get rid of popping and make sure it is running right. i got the pc3 very cheap. i'll look in the manual about the tps, but the bike feels good. be interesting to see what kind of gains are to be had with the tune. with just the thunderbike exhaust i got 130 at the wheel, but i know i have lean spots. will report when its done. and again thank you for the time you put into those directions, makes putting one in as easy as changing oil
