Peak gain from 284 to 295 hp, 222 to 232 tq. Looks like a healthy diff in the lower/mid RPM range, which is all in line with what i've heard/read

Was hoping to be in the 310-320 range but that was pretty optimistic i guess. I know the Mustang runs lower; some of the other google search results say its as much as a 10-12% difference between Mustang and a Dynojet (seems high?)

Dyno tuner said the gas was a limiting factor, said the Shell 91 gas i used was some of the worst in the area

As I swapped to an aftermarket steering wheel, I did not have the cruise control buttons for all the fancy features (my own damn fault), but I don't really need 4 maps.
