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.

Do you accept gm afm / dod / dfm disable programming 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 gm afm / dod / dfm disable programming shop in Houston I should use instead?
Most Houston 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. 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.
Will this fix a bad lifter?
No. Programming cannot repair a collapsed lifter, worn camshaft, bent pushrod, oil pressure issue, or mechanical engine noise. Those must be repaired mechanically. Disabling AFM in software does not undo damage that has already happened.
Do I still need programming after a mechanical AFM delete?
Yes. If the AFM hardware is removed, the ECM should still be programmed so AFM / DOD is disabled in the calibration to match the build.
