I have the Powerdyne with 9lb pulley and I used to see the guage right up to like 9-10 lbs of boost but now it seems that it doesn't get up that high anymore, like 6 lbs. I checked the belt tension and it seems to be within the specs from the install instructions. Any ideas on why it might not be putting out what it should. I've also noticed that sometimes there seems to be a little hesitation in lower RPMs, that never seemed to be there before. Almost like it is running to rich. Any ideas are appreciated. Thanks in advance.
