I feel lucky in that I have a 87 performance tune. He told me something in the way of its almost the same in every way with the exception of compression. I use it 95% of the time. It performs great and gets fantastic fuel mileage. Dyno tunes have some advantages because it takes into account your actual real time data.
If I'm lucky, my two days off a week are spent burning up a tank 93 octane with the 93 file tune in place. That is my very favorite thing to do. (with the exception of spending time with my wife of course)
