I only paid for my EFI Live, i didn't pay anything for my tune. I made it myself.

www.efilive.com check out their autocal it's a handheld device that let's you change your custom tunes, you can purchase that, and get a few different tunes so that you can change them for different driving. And you can also change them for when you get new parts on your truck. I believe you can also log, which will make it even better, a lot better results.

And if it says anything, i can spin 35's on dry pavement with stock 3.73 gears.
