B58 F20 F22 F30 F32 HPFP Upgrade - Dorch DE-58-1001 or DE-58-2001

Dorch Engineering HPFPs for Gen 1 B58 engines in F20, F22, F30 and F32 chassis - no guesswork, no compatibility myths. Stage 1 (DE-58-1001) flows 1.299 cc/cam rev: fast-road or mild E30-E50 builds up to ~600 whp on pump. Stage 2 (DE-58-2001) delivers 1.558 cc/cam rev: track-day E85 or high-boost pump-fuel near 700 whp.

Both retain full OEM DME control, safety logic and rail pressure stability - plug-and-play, not plug-and-pray. Includes free MHD and Bootmod3 calibration files; just select the Dorch option when flashing.
