You shouldnt run the car with it unplugged its not good for the car. I would say get the C&L 76mm kit but you will still have to get new electronics because they use the stock electronics _____________________________ 88' 5.4L Mustang GT (with a little work done to it) (in reply to ZoomZoom04) Post #: 2

When I unplugged my MAF, it idled like crap, i didnt even want to try driving it. I smelled lots of gas and the idle was going up and down a lot like almost stalling out. So I guess my MAF is okay?

Like after I drive around a little bit and give it a few revs, it runs perfect. Sometimes I get some bogging if I try to slam gears too fast. (in reply to ZoomZoom04) Post #: 5

RE: MAF - 4/26/2005 9:24:15 PM    Aliate X   Posts: 1740 Joined: 8/29/2004 From: New York Status: offline I plan to run a KB in the very near future, would a 255 be too big? The 190 supports 575 HP, but I dont really want to be limited b/c what if I dump some race gas in and crank the boost up at the track, this would be on a built motor btw.

RE: MAF - 4/26/2005 9:26:44 PM    stanglx2002 Posts: 5140 Joined: 2/15/2005 Status: offline if you are going to be getting that much HP you are going to need to upgrade the fuel lines and everything too. the 255 is going to be big but the car only pulls enough fuel to supply the car to run _____________________________ 88' 5.4L Mustang GT (with a little work done to it) (in reply to Aliate X) Post #: 12

RE: MAF - 4/26/2005 9:28:20 PM    Aliate X   Posts: 1740 Joined: 8/29/2004 From: New York Status: offline So maybe just stick with a smaller pump for now until I can afford one of those aeromotive kits or something? (in reply to stanglx2002) Post #: 13

RE: MAF - 4/26/2005 9:30:23 PM    stanglx2002 Posts: 5140 Joined: 2/15/2005 Status: offline thats a good idea a 155 wouls be a good pump _____________________________ 88' 5.4L Mustang GT (with a little work done to it) (in reply to Aliate X) Post #: 14
