Right now I have a 12-1 vortech FMU that i have been running for a while. I was just looking for a better replacement and more reliable. I have heard after a while the stock injectors will take a crap. I was hopeing someone could give me some input on what I should do or is this FMU good for keeps. After everything is all said and done will be around 12psi on a 60-1.

Most guys are using an extra injector system with an adjustable injector driver and claim good things, we have, as u know side feed injectors which have little aftermarket support. But for a lil extra fuel you can use injectors out of a 93-94 2.2 cuz they are 1lb more each. Another thing your fuel pump cannot handle a 12-1 with that high of boost even what you are running. base psi +(boost psi*12) =way too much pressure the pump cannot put out .hope this helps.

11lbs more ?? Wow I didnt know that. I will for sure get some different injectors then. I also have a walbro 255 fuel pump forgot to mention.
