Message	I did a boost leak test and my throttle body seals whistle after pumping some air into them. The gauge is only three months old but it shows that I am building no pressure at all. Doesn't even budge. But I figure if it can build enough pressure to leak out the seals after two or three seconds then it must be building some kind of pressure? Even if I pump air in for 10-12 seconds it still does not show that any pressure is built. But I believe it does because it whistles for a few seconds after I remove the air chuck. Will be checking for major boost leaks again tomorrow but I dont think there is any. All help is needed. Guess I will try to source another set of throttle bodies soon. But would this cause to build no pressure at all?
