Iowa FAQ

Common questions from customers shipping from Iowa.

How long does shipping take from Iowa to your Arlington TX workshop?
USPS Priority Mail from Des Moines, IA reaches our Arlington workshop in about 2 business days. USPS Priority routes north through the Central network; typically 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 Iowa?

Do you accept speedometer / tire & gear recalibration modules from Iowa?
Yes — we receive modules from Des Moines, Cedar Rapids, Davenport, Sioux City and the rest of Iowa regularly. With about 3.4 million registered vehicles statewide, full-size pickups & SUVs are the bulk of what we see from Iowa.
Is there a speedometer / tire & gear recalibration shop in Des Moines I should use instead?
Most Des Moines 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-region north — about 2 days each way.
Does Iowa vehicle inspection or emissions testing affect this service?
Iowa has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Iowa 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.
