I'm about to pull the trigger on a GM V8 swap in a '98 Jeep TJ. The only part that still concerns me is the chance an attendant at the emissions testing will fail it as soon as they see a mismatched VIN and "Cadillac Escalade" on their terminal.
From what I've gathered, EFILive can modify the VIN. Can it also modify the make and model? If so, does that include custom data or is it limited to a set of GM choices?
