The widely successful “Dorch Stage 2” (DS2) has been replaced with the latest and greatest creation; the DS25. This new pump is the “Stage 2.5” which has been completely redesigned and optimized from the ground up. Externally the pump packaging has been updated to provide improved hose routing for even easier installations. Internally, Dorch Engineering has re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump.
 
Just like the previous generation DS2 kit, there’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like the OEM pump. All of the safety and sophistication of the stock DME remain in place. Software changes are required to run this pump. If using MHD or Bootmod3, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software implementation via WinOLS.
