Maryland FAQ

Common questions from customers shipping from Maryland.

How long does shipping take from Maryland to your Arlington TX workshop?
USPS Priority Mail from Baltimore, MD reaches our Arlington workshop in about 3 business days. USPS Priority routes northeast through the Mid-Atlantic network; about 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 Maryland?

The customer pays shipping to us; return shipping back to Maryland 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. Cross-country northeast — about 3 days each way.
Do you accept speedometer / tire & gear recalibration modules from Maryland?
Yes — we receive modules from Baltimore, Columbia, Germantown, Silver Spring and the rest of Maryland regularly. With about 4.2 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from Maryland.
Is there a speedometer / tire & gear recalibration shop in Baltimore I should use instead?
Most Baltimore shops don't keep the bench equipment for speedometer / tire & gear recalibration — 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 Maryland vehicle inspection or emissions testing affect this service?
Maryland requires a safety inspection at point of sale or transfer, plus a biennial VEIP emissions test in most counties. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Maryland and federal requirements.
What information do you need to set it correctly?
Your new tire size and the size it replaced, and — if you re-geared — your new axle ratio and the original. We use those to rewrite the rolling-diameter and axle-ratio parameters so speed and distance calculate accurately.
Will this fix my transmission hunting after a re-gear?
Often, yes — when the ECM still thinks the vehicle has the old gears, speed-based shift points land in the wrong place and the transmission can hunt. Correcting the axle ratio in the calibration fixes the shift-point math. It does not repair mechanical transmission wear or torque-converter faults.
