Fleece Performance 01-13 GM Duramax 6.6L Duramax PowerFlo 750 CP3 (LBZ/LMM Based) - FPE-DMAX-CP3-10MM

The Fleece Performance PowerFlo 750 CP3 for the GM Duramax is a straight forward, no inflated numbers, CP3 upgrade proven to support 750 RWHP with the proper complimenting modifications. Not only will it support 750 RWHP, but it also eliminates the factory fuel flow restiction 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, as well as provide enough fuel to support 750rwhp. Features Brand new Bosch CP3 No core charge or core to return Application Notes The fuel pressure regulator will need to be scaled appropriately when installed in a 2001-2005 (LB7 or LLY) NO CORE CHARGE!!!!
