PERFORMANCE PROGRAMMERS & MONITORS

The easiest way to get more power from your truck is with a performance programmer from RealTruck.com. Installation takes just seconds: plug it into your OBDII port, push a few buttons, and your engine will come alive with more horsepower and torque. Most programmers include a monitor that allows you to keep an eye on engine performance parameters that your vehicle doesn’t display on its own.
