Montana FAQ

Common questions from customers shipping from Montana.

How long does shipping take from Montana to your Arlington TX workshop?

Do you accept gpec2 / 2a / 3 / 4 / 4lm pcm unlocking modules from Montana?
Yes — we receive modules from Billings, Missoula, Great Falls, Bozeman and the rest of Montana regularly. With about 1.7 million registered vehicles statewide, full-size pickups & 4x4 SUVs are the bulk of what we see from Montana.
Is there a gpec2 / 2a / 3 / 4 / 4lm pcm unlocking shop in Billings I should use instead?
Most Billings shops don't keep the bench equipment for gpec2 / 2a / 3 / 4 / 4lm pcm unlocking — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-country northwest — about 3 days each way.
Does Montana vehicle inspection or emissions testing affect this service?
Montana has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Montana and federal requirements.
Do you tune the module too?
No — we only unlock it. Tuning is a separate skill set and we deliberately stay out of the calibration / dyno-tuning business. After we unlock, you (or your tuner) flash whatever calibration you want using HP Tuners, EFILive, DiabloSport, or similar.
Will the unlock be detected by the dealer?
The unlock itself isn't outwardly visible — the module operates identically and reports normally to OBD-II. However, if you flash a non-stock tune AFTER unlocking, the dealer scan tool will see modified calibration values. To return to dealer-detectable-stock state, use our Stock OEM Re-Programming service.
