Instead of drilling and tapping the manifold for a vacuum source for my 3-bar map, I could make a fitting and use the original map location on the throttle body. Will this be a decent vacuum source?

Vacuum question
tip for drilling and tapping the mani without removing it: remove the vac line from the fpr. attach a blow gun into it. while you drill and tap have a buddy apply air pressure through the vac line. the chips will be blown out as you machine the hole (so wear safety glasses!).
golden eagle vac logs work well, too... though they are less than pretty in a clean, stock-looking engine compartment.
