I've been fighting this problem for months now and can't figure it out.
Issue: Leaning out 6600 rpm. Fuel pressure holds at 50+psi throughout the pull.
The car will respond to tuning changes below 6600, but no matter how much the MAF frequency is changed, it will not change above 6600.
I've tried:
Changing the load by adjusting the injector scaling, engine displacement and MAF curve.
Moving the MAF location to read less air.
Changing anything & everything in the tune that I could think might affect fuel contol.
21V BAP
My setup: Stock engine, E85, bosch 105lb injectors, KB 18V BAP, 10 psi with a Procharger D1SC, ~650rwhp
Here is the datalog:

Any suggestions would be greatly appreciated!
