having to spend too much.

Okay I have a 135i Msport manual, and I have been toying with little things, cosmetics, that I don’t care too much about, but the N54 has a major problem with building Back pressure and causing through a chain of pressure it to destroy fuel pumps. I am trying to find a way other than getting a blow off valve and replacing the pump with a higher output pump. these two things are way too expensive to do while keeping them in the factory maintenance. The only options I have are to buy an Active Autowerke BOV and Fuel pump, or Dinan. I don’t want to spend that kind of money yet, mainly because I want to do a dual cone cold air and upgrade my intercooler first. keeping cool is my perogative, I push my car hard for long periods of time and longevity is very important. Help please?
