Take control of your PACCAR engine’s performance with TM AG Tuning’s remote tuning solution for 2008–2016 trucks. This service is built to solve common emissions problems, improve horsepower, and keep your truck running the way it was meant to.

For these model years, we send you a Dimsport MyGenius handheld tuner directly in the mail. When it arrives, simply plug it into your truck’s 9-pin diagnostic port and follow the prompts on the screen. Once the readout is complete, we build a custom tune specifically for your truck and send it back to you. There’s no need to remove the ECM or visit a dealer. Everything is done remotely and easily.

Both the Stock file and the mod file are saved to the my genius. You can always flash back to stock.

If your truck shows a high soot load or the DPF is plugged, the soot counter should be reset before programming. This step is important because it prevents regen-related faults and ensures the tune installs cleanly.

TM AG Tuning’s PACCAR tuning improves throttle response, torque, and overall drivability. Many customers also notice better fuel economy and a smoother, stronger pull under load. You also get our lifetime warranty. This means if you ecu is updated by the dealer or replaced we will redelete your truck for free.

Whether you’re battling frequent regens, DPF or DEF issues, limp modes, or just poor performance, this tuning package gives your PACCAR engine the power and reliability it should have had from the start.
