Missouri FAQ

Common questions from customers shipping from Missouri.

How long does shipping take from Missouri to your Arlington TX workshop?
USPS Priority Mail from Kansas City, MO reaches our Arlington workshop in about 1-2 business days. USPS Priority is a short run north from the North Texas network; often 1-2 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 Missouri?

Do you accept speedometer / tire & gear recalibration modules from Missouri?
Yes — we receive modules from Kansas City, St. Louis, Springfield, Columbia and the rest of Missouri regularly. With about 5 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from Missouri.
Is there a speedometer / tire & gear recalibration shop in Kansas City I should use instead?
Most Kansas City 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. Regional north — 1-2 days each way.
Does Missouri vehicle inspection or emissions testing affect this service?
Missouri requires a safety inspection for many vehicles and emissions testing in the St. Louis metro area. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Missouri and federal requirements.
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.
Is this an odometer rollback service?
No. This corrects the calibration so the speedometer and odometer reflect the vehicle's actual tire size and axle ratio. It is not an odometer-rollback or mileage-alteration service and will never be used to misrepresent recorded mileage.
