go on Ebay, look for the same service number PCM/TCM for sale, doesn't matter what it comes out of as long as the it is the correct service number. Get the PCM/TCM programmed with the stock tune in them and save them for backup when you have to get service work done. I have $80 in my set.

I put a stock tune back into my 08 and the dealership said they could see that I had changed it.

No.. I'm talking about the shadow effect. I tuned my original ECM, then put a stock tune back in the original when I took it in.Originally Posted by 08z71
