Hmm, maybe I'll go back and get a 5th gear run on the DynoJet too then.

I may do the same setup, but leave the intakes stock.

The AFR on the graph he gave me was right on 14.0 at 4k RPM (first time it's stable, I think that's where he punched the throttle at honestly), and gently glides down to what looks like about 12.5 at 7.5k RPM.
By response did you mean throttle response? It revs unloaded a lot quicker than it did before, but I think that's pretty much a given. I don't think I've lost any torque at useful RPMs, although I think I've dropped some torque in the very low RPMs (3k and under -ish), just based on feel when driving.
