Upped boost, performance loss

Torque said I was running 15 psi (Using the map sensor to calculate), so I had my mechanic up the boost (3 turns on the actuator) and now torques says it's running less boost and it's definitely slower.



I have 2 month old Roose hoses so I don't think I'm having a boost leak.



I have no mods, but thought I would at least see a little gain maybe taking it back up to 17 psi, certainly not a loss though.



Any thoughts?
