That's exactly the fueling setup I have. So without any more fueling 21psi and tapering to 19psi with E40 on this setup is about all the stock HPFP can handle it seems. Nice to know. I really don't want to tinker with additional fuel mods past an LPFP upgrade, but I'd love to be able to turn the boost up to the 25psi range. I'm sure 19-21psi on the Stage 2+ units feels far different than the OEM turbos that I'm running at similar levels now though.
