so i have been looking at everyones threads, and they all seem to have the PCIII, and im over here with the yoshi PIM2. is there really any difference? im running the full yoshi exhaust and it was pretty much a package deal when i got it. i can add maps and do all the wahoo that the PCIII can, which will really make a big difference coming up soon, after my (finally decided) hotcam stage2's and a dyno tune ran by Kenz cycle out of Mesa AZ. my bike runs pretty good, but i have been noticing a little bit of rumbling as i let off the throttle. maybe the bike is running too rich, but then again, isnt the ecu and PIM suppose to detect that? its nothing bad, but i just want a clean smooth running bike that rips it up at the dunes on easter weekend. thanks!
