i am getting ready to start up my project, running the diff vacume hoses, and have a question on the TB-it has one fitting on it, upper pass/s of the body, but it looks like it is open inside before the throttle blade, where it wouldnt have vacume-or am i not seeing things right, lol
its on an LS3 intake, so there are some other vac outlets
