With the Stage 2 93 map the car hits 1116 PSI vs target of 2878 PSI at 4242 RPM This is because of the relatively high boost of 18 - 20 PSI between 2900 - 4500 RPM By comparison MHD equivalent map has about 16 - 17 PSI in the same area.
The Stage 2 E30 map gets to 1522 PSI vs target of 3100 PSI at 4357 RPM with boost 0f 18 - 20 PSI between 3200 - 3800 RPM.
Adding boost on top of that would result in hard crashing rail pressure.
I'm surprised BM3 haven't lowered the load/torque targets in their maps to better cater for the HPFP limits. They should target 170 - 175 Load Target at WOT from about 2000 RPM to about 4500 RPM then ramp it up.
