Hello, all community members. I recently brought a used truck Cummins cm2250 600 hp 1850 tq and demanded it. I used the African Overlay on the truck but when i drove it with 80k gross, I can feel vibrations happening and alot of black smoke. The coolant Temps always run around 190-210 F. Although I did used same African overlay on 450 hp truck, that truck runs great, no vibrations and barely any black smoke.

Can somebody please help me out with this truck. Any help is appreciated.
