Paccar DPF EGR DEF SCR delete

Paccar DPF Delete

The DPF system on Paccar engines is often the primary source of engine stress and decreased fuel efficiency.
Regeneration cycles consume excessive fuel and subject your turbocharger to extreme heat.
Our Paccar emissions delete tuning completely disables the regeneration logic, allowing you to hollow out the filter or install a high-flow straight pipe. The result is a cooler-running engine with significantly lower backpressure.

Paccar EGR Delete

The EGR system is designed to recirculate exhaust back into your intake manifold, but it often results in heavy soot buildup and "sticky" turbo vanes.
This contamination restricts airflow and directly impacts your engine's reliability and performance.
With our Paccar EGR delete tuning, the valve and sensors are deactivated internally.
By installing block-off plates, you ensure your engine breathes only clean, fresh air, restoring its original performance and longevity.

Paccar DEF & SCR Delete

From failed DEF dosers and lines to faulty DEF tank sensors, the aftertreatment system is a constant source of frustration and downtime.
Our Paccar SCR/DEF delete tuning fully deactivates these subsystems, allowing you to bypass the SCR filter and stop using DEF fluid entirely.
All emission related derates are eliminated, and you can finally say goodbye to the 5MPH "Limp Mode."
