CP4 HPFP Metering Valve Upgrade
This would be a mild 22% upgrade for CP4.1 pumps but has a massive 110% more flow than the standard 3.0 TDI CP4.2 that in our testing yielded a huge 68Nm torque increase and up to 10hp on our A5 3.0 TDi Quattro project
Before fitting this upgraded valve on our 3.0 TDI Project the fuel pump was unable to maintain rail pressure at full throttle and in some circumstances limp mode would occur.
Increases on the 2.0 engine are milder with only 7Nm and 6hp at the top end. With further mapping greater increases will easily be had, especially at lower RPM's
