Every file is custom written for your engine — nothing is copied, nothing is reused, and nothing is left to chance.

until the job’s done right. Most tunes are completed the same day, and everything we do is backed by a 90-day warranty, just in case. We support truck owners across the U.S., and because the service is 100% remote, you won’t lose a single hour of drive time waiting in a shop for programming.

Why Perform an EGR Delete?

The goal of the Cummins EGR system is to cut NOx emissions, but in the long run, it can hurt the engine’s reliability.

Common issues include:

• Blocked EGR coolers and valves – Restricts the flow of exhaust gas which causes the engine to overheat.
• Over time, carbon builds up in the intake, blocking airflow. This makes the engine lose power and burn more fuel.
• Costly repairs and downtime when parts malfunction.

Removing the EGR helps your engine last longer and work better. It helps the engine run cleaner with fewer regens, more power and a louder. With the right tuning, it’s the safest and easiest way to delete the EGR

EGR Deletes are great for:

• Heavy-duty towing
• Off-road or competition use
• Performance-focused builds
