Product Information

The Fleece Performance FPE-DMAX-CP3K is a modified Duramax LBZ CP3 designed to eliminate the factory fuel flow restriction that begins at 3,000 RPM. If you have a stock CP3 pump you are losing fuel flow and rail pressure after 3000 RPM, which correlates to lost horsepower when you need it most. This cost effective upgrade will allow you to maintain desired fuel rail pressure through your entire RPM range.


  • Eliminates Factory Fuel Flow Restriction
  • Maintains Rail Pressure Through Entire RPM Range

Note: The FPR Table must be rescaled when being used on LB7/LLY Trucks. This can be done through custom tuning.

CA Residents: Not legal for sale or use in California on pollution controlled motor vehicles.
