Here's why...

I can simply buy an FMU (Fuel Management Unit) which regulates and adds fuel during boost (and the stock FPR (Fuel Pressure Regulator) should be sufficient... right?). SO, it would keep the a/f where it needs to be (at about 12.5 on a boosted engine (13.5 a/f is normally best for n/a engines).

SO, FMU is the way and cheap way to go! (Only about $80, and YES it is safe for a low boost set up a.k.a. 6 psi).

So there, I dont even have to worry about sending the ECU out or anything. (BTW, I still have to keep track of the a/f ratio with a wideband! I can't just expect for a FMU to do magic; I will get the FMU at 12:1 ratio and go lower (to 10:1) if it runs to rich.

I am still debating if I want to implement an adjustable FPR... anyone want to chime in and explain why I should or shouldn't get one? (an FPR that is).
