Refund policy

Calibrations

A calibration is a licensed digital product written to your ECM. Once flashed it cannot be returned. If the machine will not accept the calibration, the install is not charged.

Parts and fluids

Unused, uninstalled parts in original packaging may be returned within 14 days of delivery with a return authorization. A 25% restocking fee applies to vendor-fulfilled parts. Fluids are not returnable once opened.
