Well I think if you go above the XDI 35, I'd start thinking about a LPFP. But tbh, you can't go wrong fortifying the 1st step in the flow of fuel regardless...One Thing I'm not 100% clear on is when you need to replace the LPFP? I'm under the impression that the OEM LPFP can handle an upgraded HPFP, is that accurate?
But plenty folks run even more mods and have been able to do ok with the stock LPFP
