Being you have a 330d does that mean you have the single twin scroll turbo? Or the twin turbo? I would upgrade turbo too since more fuel isn't going to help that but blow more smoke.

Over here our m57s injectors flow a lot for stock and you likely wouldn't need any mods unless above 700hp. The pumps do seem to have a hard time keeping up down low though. We have kits here that just became available that lets us add another hpfp so we can do dual r90 pumps which seem to be able to get our m57s close to 450hp with stock engine, add a hybrid turbo into the mix and you should be pretty close to 500whp. With meth it'll be higher too
