Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Preparing a tuned Mopar for warranty / dealer service
- ✓Selling or returning a leased Charger / Challenger / Ram / Grand Cherokee that was tuned
- ✓Failed aftermarket tune flash — module in unstable state
- ✓Removing a performance tune before emissions inspection
- ✓Recovering from a "computer says modified" warranty denial
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 the engine to stock after physical modifications (only the cal is restored)
- ✗Unlocking a GPEC2 / GPEC2A for tuning — see our GPEC PCM Unlocking service
Ford or GM module instead?
Ford and GM PCMs/ECMs/TCMs run a different toolchain and are priced at $250. Use our Ford / GM Stock OEM Re-Programming service for those.
