  • Tuners are a unique electronic device and, therefore, have a unique return process. This process necessitates physical inspection of the unit before a refund can be issued. Why? Because once a tuner is purchased and paired with a vehicle, it can only be used on that specific vehicle. This is called “vin-locking,” and prevents multiple uses of the product on different vehicles without license from the manufacturer. When returning a tuner, the tuner must first program the vehicle back to stock-mode so that it’s no longer locked to that specific vehicle. At this point, the vehicle loses the performance tune. If the tuner is returned while the vehicle still has the tune programmed to it, it will fail inspection as it cannot program another vehicle and is not in resell condition. The return will then be rejected with no return credit issued.

I was looking to be able to adjust shift points, tire size, speed limit, idle speed and be able to have tunes. Diablo Sport i3 tuner has that plus some. I have changed great ratio, tire size intake and exhaust on my truck plus other updates and I was able to balance all in good order with the diablo sport. Fuel economy has gone back up poweris used as best possible in every shift of the transmission, whether I am just driving around town or laying the pedal to the metal getting on the freeway
