EGR delete tuning for Cummins ISM
Your engine will be using clean air only, and that will result with better performance and fuel economy.

All ECM generations supported CM875 CM876.
Any vehicle brand or type!

After deleting EGR, the EGR gas flow needs to be blocked off with steel plates.
This is done to prevent EGR leaking exhaust gas back into intake.

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.
