Anyone experience a sort of reduced power mode on 2007 GM truck with supercharger and A4 trans?

It happens on part throttle and seems to regulate torque to about 400lb ft until WOT and 5200 then it seems to go away.

The timing is reduced to about 8deg. and is erratic. The injectors start running different duty cycles bank to bank.

Starts about 3600 RPM and goes away about 4800.
