It would be helpful if you could state the conditions for the bogging. Is it at launch or while car is is motion? You may be in a situation where there is insufficient fuel getting to the injectors when high boost is in especially with the smaller SC pulley. The GTP fuel injectors are rated at 33#. Have you run a fuel pressure check? You may have to run the fuel pressure tester where you can observe it when the bogging occurs.
