Which tune did you get?

Are tunes (yours?) biased one way or another (toward mpgs vs hp)? If so, which one is yours? How much hp gain did you see?

THX!

I am running a tune from Southern Speed Inc., formerly SoCal. You can find them with a Google search and there's also a thread on here that reviews those tunes. Great tune - I have no idea how much hp I've gained, but it's more than I need, for sure. If I step on the gas, it goes like a bat out of hell. I run the tune for the exceptionally smooth shifting, throttle response, and the add mpgs. Obviously I'd lose the mpg gains if I was on the throttle all the time. Something that is always tempting...
