Senior Member, on a stick
So the truck just got reflashed from VXCF43N and TQCI0AN to VXCF9N4 and TQCI1NA. Does this mean I need new tunes for my XCal 3? I would assume it does, but I want to make sure. I'm running it stock for now as the shop that worked on it (not the dealer) recommended leaving it stock to see if my lack of towing performance is improved. I'd like to be able to run it tuned again once the problems are sorted out.
