heres something that im going to try....
was talking to a guy at the Mitsu dealer and told me about this....sounds like everyone can benifit from it....even the evolution guys.... cant send direct link but here. http://www.vfaq.com/index-main.html then click Fuel. then Fuel Pump Rewires . what this does is send a constant 12V to the fuel pump. tell me what y'all think.

this is for turbo cars/or anyone who wants the fuel pump to run at 12V constant.....but reading on the DSM site at WOT ppl have seen the fuel pump voltage drop to like 10V cause the wiring is small and ****t so it cant hold voltage.....so pretty much all im doin it putting a 10ga or 8ga wire from battery to fuel pump so it gets a 12V constant.

I really don't think you need a constant 12v for the pump. I can see it requiring 12v under heavy load, but at low consumption rates, I doubt it uses that much power.
This might be a good mod for people that are taxing the stock pump, but I doubt it'll do much if anything for an NA Lancer.
Turbo guys and Evos would probably see better benefits from a higher flow pump, plus you'll void your warranty instantly messing with wiring.

This was only necessary for the DSM guys. The stock wiring to the fuel pump could not support a full 12v, so the fuel pump would not function well enough when the stock boost is raised. There is no need to do this in a turbo Lancer as you are not a "high-boost" application. High boost on a DSM is over 25psi.

Same here, Lancerguy. Not to mention my fuel cutting under boost. I don't think it's a coincidence at all. Sorry, lively. Gonna have to disagree on this one.

That is true, I didn't remember notice my pump changing it's "tune" in different situations, but now that you mention it mine did to. I still don't think it's necessary though, just because the pump is a bit overkill on 7psi any ways. The only time the pump wasn't getting enough power was at idle with headlights on and bass pumping through the amp. When you need the fuel (acceleration), the alternator is pumping away and the fuel pump was at its nice high pitch whine state.

Mine's because of bad grounds too though I'm QUITE certain. Which reminds me...I need to make a request thread with pics on grounding points for if/when I get my car back.
