Iowa FAQ

Common questions from customers shipping from Iowa.

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

Do you accept gpec2 / 2a / 3 / 4 / 4lm pcm unlocking modules from Iowa?

Is there a gpec2 / 2a / 3 / 4 / 4lm pcm unlocking shop in Des Moines I should use instead?
Most Des Moines 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-region north — about 2 days each way.
Does Iowa vehicle inspection or emissions testing affect this service?
Iowa 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 Iowa and federal requirements.
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.
What's the difference between this and your "Stock Re-Programming" service?
Unlock = removes the security so the module can be tuned. Stock Re-Programming = flashes the module back to factory OEM calibration. You'd use unlock BEFORE tuning, and stock re-programming AFTER (e.g., before selling, before warranty work, or after a failed tune).
