There is a "Dyno guesses & bench racing forum". This thread belongs there.

When you get your results then post in the "results & comparisons" section.

At WOT it's retarded. Handful on the street. I thought I was shortshifting it (because it was a new engine) but The logs showed I was shifting between 7500-7700. The powerband feels very broad and is boner inspiring. IMO this engine could easily swallow up more cam yet and still be relatively docile
Hammer - Did you get the return to idle problem fix? If you did, what was the cause?

Yes, a buddy here helped me. It was a pile of different things including tuning the IAC, timing and AFR
