Before we order your files

Send the truck details

Year, make, model, VIN, engine, transmission, current modifications, existing tuner and your goals. Tell us about warning lights, shifting complaints or existing tuning.

Separate files from hardware

Displayed prices cover tuning files only. Devices, unlocks, credits, cables, switches, installation, shipping and applicable tax are separate unless specifically included in your written quote.

Confirm access and eligibility

Four-week access starts when files are linked; cloud access ends afterward and an upgrade is needed to regain it. Lifetime access lasts for the truck’s life or until AMDP ends support. Files are VIN-locked; confirm details before purchasing because the supplier treats tuning as non-refundable.

Tuning does not repair a worn transmission or increase the vehicle manufacturer’s towing rating. We do not promise horsepower, fuel savings or warranty coverage from a generic application listing.

USD pricing checked October 16, 2026. Supplier currency pricing can change; your final written quote controls.
