Its basically a 76mm Compressor, but with an 88mm (or 96mm inducer depending on how you want to measure.) Turbine setup with a T6 flange and a 1.32 A/R. Very unlikely a 360" motor at 6,000 RPM is even close to choking on that.

Higher airflow will artificially choke that turbo. I guarantee you that if you log your exhaust pressure now, with the current engine, and later put a bigger compressor wheel in it, you would see a drop in exhaust pressure, and more power.
