Stock OEM Re-Programming in South Dakota

USPS Priority Mail from Sioux Falls, SD reaches our Arlington workshop in about 2-3 business days. UPS Ground similar. We start work the same day your module arrives, and ship back next business day with return shipping included.

USPS Priority Mail flat-rate from South Dakota to Arlington TX runs about $12. Customer pays shipping to us; return shipping back to South Dakota is included in the $99 service price.

Yes — we ship to and from all 50 US states including South Dakota. Our Arlington TX workshop receives modules from Sioux Falls and the rest of South Dakota every week.

Most local Sioux Falls shops don't offer stock oem re-programming as a bench service — they'd send the part to someone like us anyway. Going direct saves the markup and shortens the timeline. Total round-trip from Sioux Falls: typically 5-7 days.

The scan tool will see factory calibration values — it will not detect any aftermarket modification. The dealer's normal diagnostic flow does not flag a module that reads as stock. (Note: physical engine modifications — headers, cams, etc. — still show themselves through other channels. We restore the software, not the hardware.)

Helpful but not required. We capture the pre-flash data automatically. Knowing the tune vendor + approx power level helps us verify the reflash overwrote everything correctly.

Yes. The module is unrestricted after the reflash — your tuner can read and write normally. If your module was previously locked (Chrysler GPEC2/2A, GM T87A/T93, etc.) and you want it unlocked again, see our PCM Unlocking Service.
