patrickt Pat why would a vacuum gauge not work on an EFI motor? Last time I checked there was still vacuum, even with the TWM setup? Vacuum gauge still helps with intake valve problems, too much back pressure like a clogged cat convertor or muffler. I still use one about 2 times a week at work. Basic tools still work on todays latest super duper efi motors. 2 stoke motor are a different thing. Rick L.
