Please post pictures of the setup, wastegate on a centrifugal car is not typical although it has increased in popularity last few years with the coyote cars to boost the tq numbers. Also, 35 shot of Nitrous? Don't waste your time... Look at possible belt slip, check for a beat tensioner. There is also no such instance where the pulley would be maxed out, depending on impeller rpm you could be out of the efficiency range for the compressor but that's not likely only making 300rwhp.

Do you have the waste gate plumbed to a boost controller or is it simply relying on the spring? Personally I would put a 2lb spring in the gate and plumb it into a boost controller, the spring keeps it closed and the boost pressure the blower creates will seat the valve as the boost pressure increases. You will use a pair of solenoids to control the pressure on the waste gate.
