how much vaccum should a turbo 2.3 have while at 50-60 mph??
That would depend on what gear you are in and how much you are on the gas. From what my car does if you are going 50-60mph in 5th gear without hitting the gas. You should have somwhere close to 15in/hg. hope this helps. Also you should have some where close to 15in/hg at idle. That is with a stock style cam.
