Yes. Hit 511gm/s at 5,600 the yellow line and the dyn/cyl pegs there and falls off hard instead of gradually tapering off and following the tq curve like normal. Purple curve.

Drop your injector flow rate on the low number side, which should mimic high map and see if that solves your maf issue...

If you get less than 500g/s that should be okish for when the temp drops and the air gets denser

Good point. I forgot about that trick. I will have to see how I have the injectors scaled. I usually pick the scale that just fits under the injector limit and work the rest of the numbers from there. I think though I went with 52's to a oid scaling in the first place.
