New Hampshire FAQ

Common questions from customers shipping from New Hampshire.

How long does shipping take from New Hampshire to your Arlington TX workshop?
USPS Priority Mail from Manchester, NH reaches our Arlington workshop in about 3 business days. USPS Priority routes northeast through the New England network; typically 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.

Do you accept gpec2 / 2a / 3 / 4 / 4lm pcm unlocking modules from New Hampshire?
Yes — we receive modules from Manchester, Nashua, Concord, Dover and the rest of New Hampshire regularly. With about 1.3 million registered vehicles statewide, trucks & 4x4 SUVs are the bulk of what we see from New Hampshire.
Is there a gpec2 / 2a / 3 / 4 / 4lm pcm unlocking shop in Manchester I should use instead?
Most Manchester 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-country northeast — about 3 days each way.
Does New Hampshire vehicle inspection or emissions testing affect this service?
New Hampshire requires an annual safety inspection statewide, with OBD-II emissions testing for newer model years. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all New Hampshire 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.
