Certainly seems like there might be more air in the system. I will keep purge bleeding it. If I buy the adapter to bleed it into a two liter bottle, how long do I let the car run with that adapter and bottle attached?
Keep in mind that the boost will fluctuate as part of the torque management system. So depending which gear and RPM you are at it may pull some boost. I would think a 3rd gear pull should give you full steady boost. Also make sure your foot is all the way down and you are not lifting a little bit causing the valve to close and lower boost.
