If you’ve changed your truck’s tire size or rear axle gears, chances are the speedometer reading is off. Because many late-model trucks use the vehicle’s speed to also determine fuel delivery, shift points and more, TS Performance’s developed the ReSpeed speedometer calibrator and speed limiter removal unit.

The ReSPeed easily installs into your gas or diesel truck and by inputting your new tire size and/or rear axle gear ratio, the ReSpeed recalibrates and corrects your vehicle’s factory speedometer to fully optimize your engine’s performance. If your new tires have a higher speed rating, the ReSpeed can also alter your vehicle’s speed limiter by turning it off or allowing you to set a maximum speed to take advantage of your truck’s performance.

* Recalibrates tire size and/or gear ratio for accurate speed readings to gain precise engine performance and speedometer display.
* The RESPEED can turn off the speed limiter or set the maximum speed the computer sees for optimum engine performance
* Applications available for Diesel & Gas!
* Easy Installation
