I gather the stock one (when working properly) provides enough fuel to run a host of mods, but why continue to deal with the same problems over and over? Prior to buying my 135i I had a heavily modded Trans-Am and a modded turbo eclipse both of which i swapped fuel pumps before they had a chance to break. Maybe its just me but it makes more sense to spend a little bit of money on a reliable fuel pump instead of taking off mods going to the dealer then putting everything back on.
great question, i'm with you 100%! cp-e was in the process of designing and testing an aftermarket hpfp solution, but they've gone quiet about it. i think it's a tough market when you can get a free replacement pump for 120k miles as is.

the n54 is getting older, however, and more people are going out of warranty. i bet in the next year or so there will be better options in this regard.
