Wisconsin FAQ

Common questions from customers shipping from Wisconsin.

How long does shipping take from Wisconsin to your Arlington TX workshop?
USPS Priority Mail from Milwaukee, WI reaches our Arlington workshop in about 2-3 business days. USPS Priority routes north through the Central network; usually 2-3 days. We start work the same day your module arrives and ship back next business day at the return speed you chose at checkout.
How much does it cost to ship a module from Wisconsin?

The customer pays shipping to us; return shipping back to Wisconsin is selected at checkout — $14.95 standard (3-5 business days), $29.95 UPS 2-Day, or $74.95 UPS Next Day Air, flat nationwide.

Do you accept gpec2 / 2a / 3 / 4 / 4lm pcm unlocking modules from Wisconsin?
Yes — we receive modules from Milwaukee, Madison, Green Bay, Kenosha and the rest of Wisconsin regularly. With about 5.2 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from Wisconsin.
Is there a gpec2 / 2a / 3 / 4 / 4lm pcm unlocking shop in Milwaukee I should use instead?
Most Milwaukee shops don't keep the bench equipment for gpec2 / 2a / 3 / 4 / 4lm pcm unlocking — 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 2-3 days each way.
Does Wisconsin vehicle inspection or emissions testing affect this service?
Wisconsin requires OBD-II emissions testing in seven southeastern counties near Milwaukee; the rest of the state is exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Wisconsin and federal requirements.
Is this legal?
Yes for off-road / racing / non-emissions-vehicle use. Modifying the calibration of an emissions-regulated vehicle for street use violates EPA Clean Air Act regulations. We don't tune; that decision is on you.
Do you tune the module too?
No — we only unlock it. Tuning is a separate skill set and we deliberately stay out of the calibration / dyno-tuning business. After we unlock, you (or your tuner) flash whatever calibration you want using HP Tuners, EFILive, DiabloSport, or similar.
