Pretty simple question, but I can't find a definitive answer. I have a stage two fuel it lpfp, would I be able to make more power with PI or would it be the same as just the DI by itself? In a nutshell, it looks like there are various power levels for DI only with the stage two pump, but if I have PI and the stage two, does hat open up more headroom..? Or do I need to upgrade the lpfp along with PI?
