FMU or REGULATOR?

[Mustanger]

Ok, Update....
I finally got my Pro M 80mm mass air unit. The car idles great and runs incredibly strong. The only thing i'm not too sure about is, that after driving the car all day, I removed the drivers side spark plugs only to find them in brand new condition. Could this be an indication of the car running too lean or what should I look for to see if the walbro 255 lph along with the t-rex and fuel regulator are suffice to feed my 12 psi of Vortech ingested boost????????? FYI, so everyone can get a better idea, I'm running a stock 302 bottom with TFS track heat heads, Holley Systemx 2 intake, 70mm TB, Bennet racing 530 lift cam, 80mm Pro M, 42 Pound injectors with Aeromotive rails, long tube bbk's 1 3/4 with x-pipe and Vortech S trim with anderson power pipe 12pounds on the boost guage. I hope this can help in answering my questions.
