There should be no more programming to do, it should be flashed to your vehicles specs. Kind of easy to swap out, take the glove box out and it is sitting up on the right side, The hardest thing to do is to get the support bracket out. I couldn't get mine back in, just left it out since it sits in a pretty secure area anyway.


If there are mods done to your motor, the flashing only reprograms it to original specs. You would need to find somewhere to send it to for reprogramming. The dealer can't reprogram, only flash it.
