Programmers & Chips

Programmers, Tuners & Performance Chips

Programmers and tuners modify the factory ECU calibration to increase horsepower, torque, throttle response, and transmission shift behavior. From simple plug-and-play chips to full-featured handheld tuners with custom map support, a programmer is one of the most effective power upgrades for any stock or mildly modified vehicle.

OneFastShop carries programmers and tuners including handheld OBD-II tuners, plug-and-play performance chips, custom tune platforms, data loggers with tuning capability, and direct-fit tuning solutions for trucks, muscle cars, sports cars, diesel trucks, and SUVs.

Every programmer at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're adding a canned tune for more power, loading a custom tune from a tuner, or data-logging engine parameters for diagnostics, OneFastShop has the tuner.
