if it does not exceed the threshold set in the knock strength threshold map, the ECU will not pull timing because of it. Seeing knock strength values in the higher RPM range is nothing bad, the knock sensors will read general noise as well, that's why there is a threshold map |

The M370 IM is probably killing your top end. You should have picked up some decent mid range torque, tho'.
The only other thing to check is that the air feed mod isn't creating turbulence -- if MAF voltage readings aren't stable, it will be impossible to tune properly -- the MAF's are VERY sensitive to turbulence. If that's off, the fueling will be off. If all is stable, then the M370 is the problem, at least in terms of peak power.

Hey Jordo! thanx man, I figure I would lose some -6-7 WHP with the 370 Not 15 WHP but I picked up 0 in the mid range I mean zero with M370 and HFC's nothing over stock in the mid range ? The MAF vlts are stable , they slowly increase all the was till 4.37 so no dips or funky back and forth, my log is in the thread also.
