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.

Do you accept gm ecu immo-off (e98 / e80 / e82 / e84) modules from Oklahoma?

Is there a gm ecu immo-off (e98 / e80 / e82 / e84) shop in Oklahoma City I should use instead?
Most Oklahoma City shops don't keep the bench equipment for gm ecu immo-off (e98 / e80 / e82 / e84) — 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.
Will this let my swapped LS/LT run without the donor car's security?
Yes — that is exactly what the immobilizer-off does. It removes the anti-theft requirement so the E98/E80/E82/E84 runs standalone, which is what an LS/LT swap into an older or non-GM chassis needs. Your harness still has to provide power, ground, and the right inputs.
Is this a tune?
No — this is immobilizer removal only, not a calibration or performance tune. It makes the ECU run outside its original vehicle; it does not change fueling, timing, or emissions.
