Maybe not holding the throttle open all the way to allow air in? I know that always makes a big difference on my readings. I have a bike with 130 PSI with an open throttle and 60 with it closed. Didn't do it right the first time and i was so worried i was in for a rebuild before i found out i had to open the throttle blades so it could get air in. *duh*!
