it was my bike he is comparing his to... i run piolot powers 2ct and he has a d616. i think i run like 30psi in my rear. i have a powercommander on my bike but i believe it is just stock map maybe map with aftermarket airfilter but nothing crazy... now something we talked about is exhaust, he has some fmf thing and i run a stock exhaust with alsot everything a stock exhaust has just smaller so im thinking maybe back pressure could be some of it ?
