HPFP B58 Normal Non-TU

The Gen 1 B58 engine's stock High-Pressure Fuel Pump (HPFP) is designed to operate at a target pressure of approximately 200 bar (\(\approx \) 2,900 PSI), supporting roughly 450–500 whp. While it maintains this pressure at full load, it can struggle to hold 200 bar with ethanol blends (E30+) or upgraded turbos, causing pressure dips when compared to the TU.
