i am looking to use or barrow or like rent whatever a computer tuner because buyin a tuner will cost more then the parts i am puttin in can anyone help me
Each tune, Diablo/SCT or whatever, "locks" itself to the computer it is beign used on, and prevents it from being used on any other computer in another car. If computer 1 is flashed back to stock, then it allows the device to be "released" and then used on computer 2. So, basically, you're gonna have to buy one unless you need it for just like one day at the track or something.
