 92 oct map v6 3rd gear DTC wide open pull LPFP upgradeUpgraded LPFP to a DIY Fuel It 650HP. I am running a Walbro 450 alongside the OEM pump. The car is still running great on 22 psi boost target and has no issues. Now, there is just more capacity with fuel and the rail pressure no longer starts to fall off at peak power.

92 oct map v6 3rd gear DTC wide open pull The car feels good. It seems to handle 22 psi pretty well. The lowest I saw the rail pressure drop to was ~1300 right before the shift into fourth gear. However, otherwise, it was stable above ~1500 throughout the power band.

92 oct map v4 3rd gear DCT wide open pull The car felt great and seemed to handle 20 psi of boost quite well. It now has a pretty problematic over-boost code issue. Every time I get into part throttle, between 30-40% throttle cruising, it throws an over-boost code and gives me an engine malfunction light. The second log is a manual log while getting that over-boost code.

92oct map v3 3rd gear wide open pull DCT The car felt a slight bit slower because it is now hitting the boost target. This seems like a perfect 18 psi target tune. Given the LPFP issue is now solved, is there room on the table to turn up the boost?
