DPF delete involves physical alterations to the truck’s exhaust system.

Failing to perform these steps may result in exhaust blockage, which can cause low engine power and even serious damage.

EGR delete tuning for Cummins ISB B6.7

Once the EGR is deleted, it’s necessary to block off the EGR gas flow using steel plates.
This ensures that exhaust gases don’t leak back into the intake, which can lead to combustion problems.
If the EGR isn’t properly blocked off, you may experience rough engine performance, smoking, and a loss of power.
Every delete tune comes with a FREE power upgrade!
We set the power to the maximum OEM-approved rating based on your Engine Serial Number.
Power is set according to Cummins-approved specifications, with the CPL (Control Parts List) number as our primary reference.
Perfect for fleets and daily drivers, offering a safe and reliable performance boost.
