Curious if vacuum plus manifold pressure reading should be roughly equal to barometric pressure? Running Torque and watching realtime data I typically see a vac reading of 11-22 or so depending of course on load, with a manifold reading of 3-9 on average. I would expect that the two together should be roughly equal to barometric depending on load, and wonder if I may have a vac leak driving my gas mileage down.
Any thoughts or info are appreciated.
