Egg roll is right air psi opens the wastegate and that is the first test I would do. It also sounds like you are running on wastegate pressure are you sure the pill is in the line? Your afr's should be at 14.7 when not in boost and go up to a max of 10.5 to 11.something depending on the tuner. Im not sure what cobb does.
