Introducing the all-new TrailDash 3 for Jeep Wrangler and Gladiator! Built off the success of our TD2, the all-new TD3 offers a state-of-the-art display with a 5 full-color screen with edge-to-edge swipe technology. Using the latest monitoring technology, TD3 offers a clean and sharp display unlike anything on the market for Jeep owners today.

After installing your tune, start the vehicle. Let the vehicle run for more than 3 seconds, and test throttle response. The vehicle shutting off after ~3 seconds, or having a dead pedal indicates that there was an issue reading stock data and/or writing stock data to unlocked PCM. If throttle response is good and the vehicle stays running, please continue by shutting off the engine, returning the ignition to ON.
