Which one do I want? Do I need anything else to install it? Is it easy to install? Anything I should know? Thanks for the help.
What do you have on your car right now?The S-FMU is very good but around $275. If you can't afford that you can buy a regular FMU with whichever ratio you want.

I dont know what ratio to get....that is my my question.
Depends on how much boost you will be running.5-9 psi a 8:1 or 10:1 would be fine. Anything over you should just get an S-FMU anyway.
I am just getting a s-fmu....Is there only one or is there different ratio's?
sfmu is adjustable.
