Look local too. Buying a tune off of the interent also means not getting top results performance wise. I have a local guy, thats known all across the south for tuning mustangs doing mine. I can't remember what he called the program he is using, but he has to cut out the back of my computer casing, and add a chip to the mother board that will stick out the back out the computer. Then, once I work out any bugs and leaks I will go back to his shop and dyno tune, He will pull it until he is satisfied with the outcome.
I'll update you monday on what the program he is using is called. That's when I pick up the computer.
