Unlocking Peak Performance: CPX Or DCR Pump?

No matter how you use your 6. 7l power stroke, the dcr pump provides a significant upgrade in reliability and performance over the factory cp4 system. Cpx requires zero modifications. The dcr pump produces an unwanted vibration when bench tested compared to the cpx. The cpx now that the bucket is pinned is essentially problem free. There is no cp3 conversion available for the 6. 7 engines because the pump will not physically fit in the valley of the block.

Just watched a video from rcd performance seem like the right direction they appeared to have upgraded the cp4 and call it the cpx high pressure fuel pump.
