Just a word of warning/advice. Make sure all of your vacuum lines are zip tied. I thought mine were but at the track last night before the 1/8th my boost gauge dropped to zero and the green alky light went off. I got worried so I lifted and I heard a pop when I saw my 02's go to 735! After checking everything it turns out that the vacuum line connection near the vacuum block that goes to the MAP sensor blew off. Since I was running alky it stopped flowing since it saw zero boost! I just about wet myself and ended up with a 12.80 @ 79 MPH.
