I have a PPE Standard Xcelerator for my 2004 dodge cummins. I had a little problem with my truck and i thought just to narrow the problem down, i returned the truck to stock on my PPE. Started truck to make sure it started. Started just fine. I went in and changed the tire size following the instructions. Unplugged it. i drove 3 hours got home and tryed to reprogram the truck with the PPE and now it is saying it is VIN locked. But it is VIN locked to my truck.. Does anyone know what i could try to get it to work?? I talked to a guy this morning at PPE but he was far from helpful.. Didnt want to talk on the phone.. Very rude The only thing he would say is send it in.... ![Mad :mad: :mad:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
