"teed" into the line from the aneroid to the vacuum amplifier ran the car for a few miles and under load, seemed to level out at around 9 psi, highest I saw was 9.5 psi. Did not seem to want to go any higher - I guess this is an indication that the waste gate is opening. Looks like the boost works. Could the "vent" line that allows it to go to 0"Hg vacuum be plugged? I will test the vacuum pressure again after I have replaced the brake vacuum line check valve (with the "fixed" orifice size). I will not be surprised if that is not some of the problem because of some diyer "cleaning" the line out

The car ran good during the whole test.
