Texas FAQ

Common questions from customers shipping from Texas.

How long does shipping take from Texas to your Arlington TX workshop?
USPS Priority Mail from Houston, TX reaches our Arlington workshop in about 1 business day. USPS Priority routes through the North Texas distribution network; 1 day from most of the state. 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 Texas?

Do you accept gpec2 / 2a / 3 / 4 / 4lm pcm unlocking modules from Texas?
Yes — we receive modules from Houston, Dallas-Fort Worth, San Antonio, Austin and the rest of Texas regularly. With about 22.8 million registered vehicles statewide, full-size pickups & SUVs are the bulk of what we see from Texas.
Is there a gpec2 / 2a / 3 / 4 / 4lm pcm unlocking shop in Houston I should use instead?
Most Houston 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. Same-state — fastest possible round-trip.
Does Texas vehicle inspection or emissions testing affect this service?
Texas requires an annual safety inspection program statewide, with OBD-II emissions testing in 17 metro counties. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Texas 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.
