Is there a gm afm / dod / dfm disable programming shop in Nashville I should use instead?
Most Nashville 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. Cross-region northeast — about 2 days each way.
Does Tennessee vehicle inspection or emissions testing affect this service?
Tennessee discontinued its county emissions testing programs and has no statewide periodic safety inspection. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Tennessee and federal requirements.
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.
Do I need to remove the engine heads?
Not for a software disable only. Removing the heads is normally part of a mechanical AFM delete or a lifter replacement job, not the programming step.
