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

The Fleece Performance Duramax 10mm stroker CP3 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.This Part Fits: Year Make Model Submodel 2006-2010 Chevrolet Express 2500 Base 2006-2010 Chevrolet Express 3500 Base 2001-2005 Chevrolet Silverado 2500 HD Base 2001-2006 Chevrolet Silverado 2500 HD LS 2001-2010 Chevrolet Silverado 2500 HD LT 2007-2010 Chevrolet Silverado 2500 HD LTZ 2004,2006-2010 Chevrolet Silverado 2500 HD WT 2001-2005 Chevrolet Silverado 3500 Base 2001-200
