We’re proud to introduce our latest 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 for even easier installations. 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:



This is a complete plug-and-play kit to support up to 550whp on E10 fuel (this number can vary quite a bit depending on tuning strategy and the blend of ethanol). 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 contact sales@urotuning.com for further assistance.
