Dorch Engineering DS15 HPFP Upgrade for BMW E/F Series N55

Introducing our latest generation of pumps: the DS15, our “Stage 1.5”. Redesigned and optimized for improved hose routing and increased volumetric efficiency, this 250 bar capable pump will provide gains at 200 bar.

This fully plug-and-play kit can support up to 550whp when using E10 fuel (this outcome is contingent on tuning approach and ethanol blends). Simple installation, no adjustments or modifications required. This kit works with full DME control, maintaining OEM safety & sophistication. Tuning software changes must be employed; if using MHD/Bootmod3, just choose the pump upgrade; otherwise send your .BIN to tuning@dorchengineering.com for WinOLS software changes.
