240 turbo HELP!!!!!!!!!!! 200 1984

You can use the vacuum portion of your TURBO gauge to test for a exhuast restriction.

Get the engine totally warm and observe the vacuum reading at idle, now bring the rpm's up to 2000 and hold it there.

If the vacuum reading decreases at 2000 rpm's (that would be moving upward toward the yellow) this would indicate an exhuast restriction.

Staying the same or an increase (moving downward) would be O.K.
