Product Description

ATTENTION MHD USERS! This is a limited sale on the XDI 35 HPFP (for N55) upgrade for MHD users ONLY! Please note: You must use MHD as your means of flashing the HPFP parameters onto the stock DME. TTFS is not providing any flashing parameters on this order, all parameters must be flashed VIA MHD using OTS or MHD Custom mapping.  

The installing of the pump is fairly easy but, it must be accompanied by custom base tuning to work correctly. If you are ordering this pump option it is under then assumption that you are using MHD to flash all the pump parameters. This can be done with MHD OTS or MHD Custom tuning with the tuner of your choice. Please note this Pump does not include a MHD licence or any maps.

We are proud to offer the N55 community the first ever factory like fuel system upgrade. While the factory fuel system is adequate for stock vehicles, these engines quickly run out of fuel even with the most basic performance upgrades. To help combat this we are introducing the first High Pressure Fuel Pump for the N55 direct injection engines! Our extensive work with Xtreme-DI has revealed this pump can expand the tuning and performance opportunity of your N55 motor. This is a complete bolt-in factory replacement upgraded and comes with everything needed to make installation easy.
