Sorry to thread jack, but it may help out others..
I have found that in California when I go to get the truck smogged I cannot have anything on the ECM besides the factory tune. So if I swapped a manual into my truck, and bought a manual ECM, would it fail because it shows a different VIN? Or if I reflashed it, would I fail because it doesn't have the factory tune?
