A stock CP3 starts to choke fuel flow at about 3,000 RPM, so rail pressure and power fall off right where you want them most. Fleece's CP3K removes that limit, so you hold the rail pressure you ask for across the whole RPM range.
For the 5.9L, the CP3K is a brand-new Bosch 6.7L-type CP3 that Fleece modifies, and it comes with the fittings and the high-pressure line to adapt it.
Owners of 2003-2007 Dodge Ram 2500/3500 5.9L Cummins trucks who are losing rail pressure at higher RPM.
