did a comp check, a/f is good, fuel pressure is good, still no luck. before i had my pi heads ported and added cams a dyno'd 254/293, it dyno'd 225 a couple wks ago, nothing is wrong mechanically. my cams are hp regrinds, i haven't talked to anyone whose had issues with them? maybe it's the tune?? i guess there's more to a tune than just getting the a/f right?? any help is appreciated.
