I am just looking for some general feedback...
I am running a fairly stock puch maxi with a 62 jet and a biturbo exhaust. The ped can get up to about 25 with the pipe on, but if I take the pipe off acceleration is MUCH better and I can get up past 35.
Thoughts on what I am doing wrong here. I recognize running without an exhaust is a bad idea, any safe ways I can get it up to speed by modifying the biturbo I have on there?
