Vacuum-At an idle speed of about 700 rpms I pulled 10-12 HG's of vacuum. If I had brought my idle up to about 900-1000, which most people do for my cam, I would pull 15. I can't hear any vacuum leaks and all the hoses are intact and connected. The car doesn't surge or act strangely, except every once in a while when the cam tries to do its own thing.
Oh and this style MAF uses the heating element-type wire? Never cared much for that kind....I always preferred the type that vibrates with the incoming air. Wonder which is more accurate.....
