Dorch B58 Gen 1 DS15 HPFP Upgrade

From the creators of the world’s first B58 direct-injection fueling upgrades, comes our next generation of pumps. Our widely successful “Dorch Stage 1” (DS1) has been replaced with our latest and greatest creation; the DS15! This new pump is our “Stage 1.5” which has been completely redesigned and optimized from the ground up. Externally we’ve updated the pump packaging to provide improved hose routing. There’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like factory. Internally, we’ve re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump. This is now a 250 bar capable pump and here’s the gains to be expected at 200 bar: 

Software changes are required to run this pump. If using Bootmod3, MHD, or MG Flasher, simply check the box for our pump upgrade when flashing. Otherwise, please contact sales@broxtuning.ca for further assistance.
