Dorch Engineering B58 Gen2 DS3 HPFP Upgrade

OVERVIEW

After significant R&D, Dorch is proud to release the highest-flowing single-pump solution on the market for Gen2 B58 (B58TU): the DS3 (Dorch Stage 3). This is the largest bore size and highest-flowing pump to date, supporting incredible power with just a simple HPFP swap — with 20% more fueling gains than the DS25. As usual, there's no cutting, no bending, no crimping. This kit drops right in with full control from the DME, just like factory.

SPECS

• Largest bore size, highest-flowing single pump Dorch offers for Gen2 B58
• 20% more fueling gains than the DS25
• Requires larger-than-stock injectors to operate at full potential — OEM S58 injectors are a good budget pairing for the DS25, but the DS3 needs even more injector than that
• Combine with Dorch injectors and a cam solution for never-before-seen 4-digit direct-injection power
• Plug and play — includes a 350 bar capacity hardline for direct connection to your fuel rail
• Lifetime warranty

PARTS INCLUDED

• 1x DS3 high-pressure fuel pump (fitment per variant)
• 350 bar capacity hardline

TECH RESOURCES

• Software changes are required — check the box for the Dorch pump upgrade in Bootmod3 or MHD, or send your .BIN file to Dorch for WinOLS implementation
• Gen2 B58 (B58TU) only — not compatible with pre-2020 Gen1 B58 vehicles; Dorch offers a separate Gen1 DS3 kit for those platforms
