I think your best bet is to have someone like JET do the work, If I remember right, you send them your ECU, takes like a day, and they tune it for you, you just buy a JET box, they do the programming and it goes back in the car. Pretty safe I would say. You send it in after you have done your MODS, turbo or anything, think its like 400 bux, 10 to 20HP gains.
