Idle is fine and it also runs fine when crusing but when I mash the gas I'm only getting about 6psi of boost as opposed to 11psi before. The boost gauge seems to be going a little lower on the vacum side but only after I gave it gas. When it idles the gauge is where it should be. My car is so slow right now please help.
