7 psi do i need a harness or not? just FMU thast it?
 

-someone is selling a kit telling me as long as i keep it under 8 psi i need to obdII to obd I conversion harness as long as I do FMU and stay under 8 psi ture or not.

up to 6 psi its fine with a FMU of 12;1 and stock ecu obd correct? I have a 1996 so i think i have a obd 2a. the thing is that i don't know squat about mapping etc

fmu's are garbage you cant trust them to much, if you really care about your motor you are going to want some decent fuel management such as uberdata or turbo edit.

i would take an fmu over a blue box...but they are both basically worthless
