Alright gang here it is;

I just installed hmf exhaust, k&n airfilter, snorkel, and jets 145r & 142 f I think I have every thing dialed in right because got more power and no pops or misses when I'm on the throttle. But on top end I lost a couple of mph. This is really not to big a deal but I wondered has this happened to anybody else. Also I noticed that when I start to give it throttle my belt starts to squeak. I just wanted to make sure does this mean my belt is loose and do i need to take out a spacer? Would a loose belt be the cause of the lost mph? Any feedback would be extemely helpful
Thanks

 

Did the same HMF,K&N,Snorkle,145,142, 1,1" hole in airbox.10% more power. Do the Black EPI spring With no shims you should be good to go.Dont forget the Progressive springs out front.

 

YES, you will lose speed from a worn belt. if it is squealing adjust it, go with the black spring, if you don't have it, that will help with wear. You also may be over revving..
