That's disappointing to hear. Part of the appeal of using DI is because of it's in-cylinder cooling benefits. Resorting to using older, albeit familiar, tech like PI is just a bandaid, not really much of a solution.
In other platforms I have seen development for HPFP internals that handle higher loads and are simple internal swap kits for a very fair price point, not exactly an entire replacement. I figured that something would be available considering BMW's in general are more up market anyways, and certainly a healthy enthusiast market. Ah well, gotta work with what you got. Are these entire fuel systems, or are we just talking larger injectors and a higher volume LPFP?
