Why Illinois customers mail in stock oem re-programming (ford / gm)

Illinois has roughly 10.5 million registered vehicles, and trucks, SUVs & imports make up much of what Chicago-area shops and owners mail us. Stock OEM Re-Programming (Ford / GM) is a bench job most Chicago shops don't keep equipment for, so owners and trade shops across Illinois ship it to a specialist. Cross-region north — about 2 days each way.

How long does shipping take from Illinois to your Arlington TX workshop?

Do you accept stock oem re-programming (ford / gm) modules from Illinois?
Yes — we receive modules from Chicago, Aurora, Rockford, Naperville and the rest of Illinois regularly. With about 10.5 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from Illinois.
Is there a stock oem re-programming (ford / gm) shop in Chicago I should use instead?
Most Chicago shops don't keep the bench equipment for stock oem re-programming (ford / gm) — 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 north — about 2 days each way.
Does Illinois vehicle inspection or emissions testing affect this service?
Illinois requires emissions testing in the Chicago and Metro-East St. Louis areas; downstate counties are exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Illinois and federal requirements.
Will this fool the dealer's scan tool?
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.)
Do I need to tell you what tune was on it?
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.
