Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Preparing tuned vehicle for warranty / dealer service
- ✓Selling or returning a leased vehicle that was tuned
- ✓Failed aftermarket tune flash — module in unstable state
- ✓Removing performance tune before emissions inspection
- ✓Stock-class racing — need verifiable OEM calibration
- ✓Recovering from "computer says modified" warranty denial scenarios
Won't fix:
- ✗Hardware-failed PCM (this flashes software, doesn't repair the board)
- ✗Modules with no OEM calibration available (rare; we tell you upfront if so)
- ✗Restoring engine to stock after physical modifications (only the cal is restored — not headers, cams, etc.)
