Thanx for the info guys, but i think u have given me more credit than i deserve. I'm kinda a newbe when it comes to mustangs.

Why is it that i will need a fuel mangement unit with 30lbs injectors, and won't need one with 42lbs injectors? Does a fmu add more fuel as the boost gets higher? I no i will need to reca;ibrate my mass air meter for the new injectors. Is it hamful at all if u don't have the right size injectors?

I havn't heard much about the fuel pressure regulator u have suggested, is it a well proven brand? I was considering a bbk, or accel?

As for the intake i have decided to set it aside for now.

Kirban is one if not the best, the others tend to leak. the FMU makes up for the lack of fuel, and is basically really not as accurate as just getting 42lb injectors. As for recalibration of the air meter, what brand do you have? If it is a PRO-M, yes you will need to recalibrate it, if it is a C&L, just buy the sampling tube. and yes the injectors and air meter should match, or you will run into tuning and driveabilty problems.
