I just bought a superchips programmer at Quadratec's tent sale yesterday and before doing anything with it, I downloaded the latest updates to it. I installed the 87 octane tune in my jeep ( I have it filled with 87) and while the throttle response is much better and the tranny seems to shift a little firmer, it doesn't seem like much of a power difference, and it pings really bad from 1/2 throttle on when climbing hills or holding the revs pretty high. I'm guessing I don't feel much power increase because its trying to pull back on the timing when it starts pinging. Is it just crappy gas, or does my AFE drop in filter and hushpower muffler make that much of a difference?
