as some of you know I just had my fmic installed,after we did everything checked the vacuum at idle it was at 21 which is very good,and at wot it was pushing 13-14 lbs max boost. prior to that it was only boosting 8 lbs but that was due to my bypass not closing all the way,we felt we got it to close all the way by the fact that is pushed good max boost. well now it max's 11 lbs boost. So is there still something wrong with my bypass. figured it was highly unlikely with 21 at idle that I had a vacuum leak. any idea's or do most of you feel I still have a leak?
