Yes, I'm tuning with 91 octane here, so that's all the advance I can run in most spots.

Unfortunately the correlation between MAF voltage and TP is not always exact - the maf transfer is not linear.

Luckily there is a group of moded MAF for the 4.6 Ford Mustang and others where you can slipslide a few graphs and find some that kinda fit close. It would be nice if someone ACCURATELY Flow benched a Q MAF to create density vs voltage graphs that are more exact but............ 4.5 volts might be 255 gms, 4.4 volts seems to be around 240-235 grams per second.4.3 ~~220. 4.2 ~~200...........the difference between 4.3 and 4.4 volts might be the ability to create 30 HP assumming correct AF ratios.

A rough rule is 1.25 SCFM per HP

I have the MAF transfer graphs directly from the ECU code, but it's not in a format that translates directly to gms.
