Tuning with PPEI
PPEI recommends Fleece pumps for big Cummins builds, and we run them on our own trucks. A 12mm stroker only pays off when the tune knows what to do with the fuel. With PPEI 5.9L Cummins engine tuning built around that extra volume, the build makes real power with sharp throttle response, and it does it efficiently instead of just making smoke.
