Guys, I did a file for a guy and he gave me the VIN number incorrectly. One or two of the digits did not match. So, as you can imagine, it would not work and after going through the issue we went over the VIN he gave and realized the issue. Resent tune with VIN corrected and the truck started and ran fine BUT...now we have the CEL of course which I assume is from the VIN mismatch originally in the first tune. Is there any way to get this CEL off or is my only option a Dealer visit and new flash and start over? Thanks guys!
