Colorado FAQ

Common questions from customers shipping from Colorado.

How long does shipping take from Colorado to your Arlington TX workshop?
USPS Priority Mail from Denver, CO reaches our Arlington workshop in about 2 business days. USPS Priority runs northwest from the North Texas network; roughly 2 days. 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 Colorado?

Do you accept gm ecm / pcm — programmed & ready to install modules from Colorado?
Yes — we receive modules from Denver, Colorado Springs, Aurora, Fort Collins and the rest of Colorado regularly. With about 5.3 million registered vehicles statewide, trucks & 4x4 SUVs are the bulk of what we see from Colorado.
Is there a gm ecm / pcm — programmed & ready to install shop in Denver I should use instead?
Most Denver shops don't keep the bench equipment for gm ecm / pcm — programmed & ready to install — 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. Regional west — about 2 days each way.
Does Colorado vehicle inspection or emissions testing affect this service?
Colorado requires emissions testing in the Denver-Boulder Front Range metro region; rural counties are exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Colorado and federal requirements.
Will it run correctly right out of the box?
Yes — it is flashed with the current factory calibration built against your VIN, so the engine, transmission, axle ratio and emissions content already match your truck. Install it, run GM's security relearn (three 10-minute key cycles), and drive. A crank-relearn may be advised on some applications; the instructions ship in the box.
Can you load a performance tune instead?
This product ships factory calibration only. If you want a performance calibration afterward it is yours to do — the module is not locked against it. We also sell dedicated bench services such as DOD/AFM delete and speedometer recalibration if that is what you actually need.
