Low vacuum reading?
Hey all,
I have a question regarding my vacuum pressure reading on my 2004 fxt. Today I installed an autometer phantom series boost gauge. The install went great so there are no questions there. My only problem is that I'm seeing a low reading on my vacuum pressure. At idle the needle sits at a steady 15. If I blip the throttle it goes up a tad, drops to 18 for a sec then goes back to 15. When the car is off it sits at 0 and at WOT it'll go up to a tad over 11 (right where it's supposed to). When I turn the AC on it'll go up to 14ish. The car is still running a stock map but I've upgraded the intake, tmic (w/ samco hoses), and cbe. I've listened around for vacuum leaks but so far I haven't heard anything. The car runs fine but I'm kind of worried I might have a problem. Any input? TIA
