After significant R&D, we’re proud to release the highest flowing single pump solution on the market, the DS3 (Dorch Stage 3)! This is our largest bore size and highest flowing pump to date, supporting incredible power with just a simple HPFP swap. The DS3 is the same reliable, OEM drop-in solution you’re used to, but with 20% more fueling gains than our DS25! As usual with our kits, there’s no cutting, no bending, no crimping, an included OEM quality high pressure line, etc. This kit drops right in with full control from the DME, just like factory. Combine this with our game changing injectors and one of our cam solutions and you’ll have never before seen, 4 digit direct-injection power!
NOTE: While the S58 OEM injectors are a great budget pairing for the DS25, the DS3 requires even larger injectors to operate at it’s full potential.

Software changes are required to run this pump. If using Bootmod3 or MHD, simply check the box for our pump upgrade when flashing (coming soon). Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software implementation via WinOLS.
Beyond the pump performance, why choose Dorch?
