Hey guys, I've got a handheld question for you. I'm taking my car in for routine maintenance at the dealership. I've put my tune back to stock, and configured my intake, by air raid, to stock specs. I did this just in case they had to do any maintenance on the engine or transmission and I didn't want them to screw anything up. (Just being on the safe side) My question is besides a ECU change, does the dealership during maintenance , ever install updates to the ECU that would cause the handheld not to recognize it when I put the custom tunes back in? Thanks for any input! PS this is not a warrantee question.
