Ah, that old problem of pumping losses. It takes more energy to drive a larger compressor. With that same old tech turbine your exhaust backpressure has to rise to get that extra airflow.
Do you have a baseline of pressure differential across your engine?
HP = positive pressure differential over engine at a fixed manifold pressure.
