Dorch Engineering S55 Lift Kit - HPFP Upgrade for BMW F8X M2 M3 M4

Our Dorch Engineering HPFP Upgrade for BMW F8X M2 M3 M4 offers an unmatched, game-changing advantage to S55 users. Instead of a standard HPFP upgrade, we utilized state-of-the-art techniques & tools to create a higher-flowing, easier-to-tune solution for a fraction of the cost. We've successfully increased fuel flow by 38% without any modifications to the OEM pumps, maintaining longevity & reliability. Installation is simple - just drop in, no cutting, bending, or crimping required. DME mapping remains OEM, and our lifetime warranty provides security. Get the highest flow rate & emissions pass without breaking the bank.

Software changes are NOT required to run this upgrade. However, we do have preset optimized maps available via Bootmod3 and MHD. Simply check the box for our “Lift Kit” upgrade when flashing.

NOTE: The S55 fuel system is very much limited by the injectors. In order to see the true benefits of this kit, it is highly recommended to upgrade to the larger S63 EU5 Injectors. These are readily available OEM BMW injectors proven to support 800whp on full E85.
