Oklahoma FAQ

Common questions from customers shipping from Oklahoma.

How long does shipping take from Oklahoma to your Arlington TX workshop?
USPS Priority Mail from Oklahoma City, OK reaches our Arlington workshop in about 1 business day. USPS Priority is a quick hop north from the North Texas network; often next-day. We start work the same day your module arrives and ship back next business day at the return speed you chose at checkout.
How much does it cost to ship a module from Oklahoma?

The customer pays shipping to us; return shipping back to Oklahoma is selected at checkout — $14.95 standard (3-5 business days), $29.95 UPS 2-Day, or $74.95 UPS Next Day Air, flat nationwide.

Do you accept gpec2 / 2a / 3 / 4 / 4lm pcm unlocking modules from Oklahoma?
Yes — we receive modules from Oklahoma City, Tulsa, Norman, Broken Arrow and the rest of Oklahoma regularly. With about 3.6 million registered vehicles statewide, full-size pickups & SUVs are the bulk of what we see from Oklahoma.
Is there a gpec2 / 2a / 3 / 4 / 4lm pcm unlocking shop in Oklahoma City I should use instead?
Most Oklahoma City 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. Neighboring state — typically 1 day each way, the fastest non-Texas round-trip.
Does Oklahoma vehicle inspection or emissions testing affect this service?
Oklahoma 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 Oklahoma 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.
