I thought of that, and that is why I changed it. Since it is a multiplier, it is actually making it richer at pressures over ambient. If you're running an ECU with A00D, A01D. B01D, or D00D CAL ID's you can give this tune a try and see if it is leaning out at high RPM's. This tune should give you MUCH better highway mieage. The D00D definition file didn't have the Port compensation table defined, so it hasn't been changed in that tune, just the AVCS tables have been changed. The other three tunes have the port compensation adjusted, as well as the AVCS Intake and Exhaust tables for maximum efficiency from .3 - .6 load, and I'm still working on maximum power for loads above that. It runs well around town, good launch, shifting, and cruising. On the highway it can cruise below .4 load and get good mileage. I haven't got any tunes or maps for MT's yet, but I do have plans for them in the future.
