Well what happens is you go to their website and place your order and then in a day or two they will email you a form to fill out to say what mods you have and what fuel you run etc. then once you fill it out, they will email you the tune in a day or two.
I'm assuming depending on what mods you have, they give you a tune that can make the optimal amount of power for those mods.
