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.

Do you accept gm afm / dod / dfm disable programming 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 afm / dod / dfm disable programming shop in Denver I should use instead?
Most Denver shops don't keep the bench equipment for gm afm / dod / dfm disable programming — 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.
Can AFM / DOD be disabled by programming only?
On many supported GM Gen 4 V8 ECMs, AFM / DOD can be disabled in the calibration. This keeps the system present but disabled so the engine stays in V8 mode. Support depends on the ECM, operating system, and calibration, which we verify before accepting the order.
Can this be done on the bench?
Yes. We program supported GM ECMs on the bench using a proper bench harness and a stable, regulated power supply, then test communication before the module ships back.
