Do i need any mods with a PPE xcelerator tuner?
So I have an 03 duramax. I was thinking of buying a ppe xcelerator tuner for it, but my question is. Do i need any other mods? Will the ppe xcelerator destroy my stock tranny? Or are there any other tuners that you would recommend for a stock truck? any ways i'm pretty much looking for the best tuner without having to make any mods to my truck.
