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. 

 

Software changes are required to run this pump. If using Bootmod3MHD, or MG Flasher, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to [email protected] for the appropriate software changes via WinOLS.

 

Beyond the pump performance, why choose Dorch?

Poor quality.
The little nodes on the ring break off and my dog ate them. Hopefully it will pass.

Not for super aggressive chewers even though..
My 10 month old Mastiff chewed this pretty well for a couple hours but I had to take it away from him as it has pieces missing and its not a complete ring anymore. Definitely not indestructible or even close to indestructible. I was sure hoping though. But nope.
