I'm currently rebuilding an f4r engine and am in need of new cams. I am also a student so money isn't my greatest asset unfortunately. I've seen a set of re-profiled 'fast road' cams on the Piper website for a decent price however I've don't know anyone with any experience with re-profiled items, if anyone knows anything it would be helpful.
Also I didn't think the ecu would have to be remapped as they are only 'fast road' and aren't giving a massive increase in lift but this is what the website states. Hmm
