LOL sorry man... haha i now how to make one i just am to lazy so i purchased one from boostpro.net it comes with a gauge and evrything not bad. 20 bucks. but if any one has one at there place and wouldnt mine me using it for 10 min, give a shout. im sure somthing is messed up.

my boost gauge normaly at idle reads -20 and boost to 14 but when i let of the boost it drops below -20 to -28 and stays there till im back at idle or back on the pedel. does that sound like a boost leak to you?
