North Carolina FAQ

How long does shipping take from North Carolina to your Arlington TX workshop?
USPS Priority Mail from Charlotte, NC reaches our Arlington workshop in about 2-3 business days. USPS Priority routes east through the Southeast network; usually 2-3 days. We start work the same day your module arrives and ship back next business day at the return speed you chose at checkout.

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

Is there a gpec2 / 2a / 3 / 4 / 4lm pcm unlocking shop in Charlotte I should use instead?
Most Charlotte 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 southeast — about 2-3 days each way.
Does North Carolina vehicle inspection or emissions testing affect this service?
North Carolina requires an annual safety inspection statewide, with OBD-II emissions testing in a set of more populous counties. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all North Carolina 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).
