[QUOTE="mwolson, post: 12951293, member: 16006"] You must hook it up after the blower so it sees vacuum AND boost. If you hook it in front of the blower so it only sees vacuum, when you go into boost, you will not see enough fuel pressure and you'll go lean. If you are running an FMU (AKA FMB), I'd ditch it, and go for a custom tune. Relocate your IAT sensor to after the blower before you install the blower too. Here's how I did it: [url]http://www.classictiger.com/mustang/IAT-IMRC/IAT-IMRC.htm[/url] Set your FRP at 39PSI (you didn't really need an adjustable one.) I have no idea what line you are talking about when you say, "the vacuum line that connects to the intake rite after the maf". FYI, that is metered air, not vacuum. Vacuum doesn't happen until after the throttle body. Got a picture? [/QUOTE]
