12:1 FMU for stock injectors/fuel system <-- make sure you use a high-pressure fuel pump!

X:1 means the FMU will bump up your fuel pressure by X psi for every 1 psi of boost

I have a brand new Vortech 10:1 FMU for sale if you need one.

ok i was told today that a 8:1 would be ideal, i am going to be using the stock fuel pump, was also told that 12:1 will give way too much fuel. input?

Its hard to say if your getting enough fuel without a wideband O2. Otherwise your tuning blindly. 10:1 is pretty common probably because its in the middle.

haha i know i already looked at it, might be interested depending on what i plan on doing for fuel managment, and i would be using a wideband o2 on a dyno for tuning so i should get a pretty good idea

Well if you plan to "tune" the fuel pressure according to your wideband then your going to need an adjustable FMU which would require a more expensive FMU such as the Vortech Super Blue FMU or the Jackson Racing FMU.
