Cummins EGR delete kit, The EGR system reroutes exhaust gases back into the intake, leading to the buildup of soot in the intake manifold over time. This accumulation can cause the Variable Geometry Turbo (VGT) vanes to slow down and become less responsive, restricting airflow and negatively affecting engine performance. By performing a Cummins EGR delete, you can eliminate the EGR valve and its sensors from the ECM software, using block-off plates to stop exhaust gases from entering the EGR manifold. This modification can significantly improve engine efficiency and reliability | Industrial Powerup.
