Hey guys, over the past year we've worked with a number of customers and shops that chose the XDI's high flow pump as their HPFP upgrade. They have two versions available, the XDI-35 and the XDI-60, both of which outflow the OEM HPFP pump on the N55.
As of now any bootmod3 user looking to go with an XDI HPFP upgrade can go into any of their maps (custom or OTS), use the map configuration screen and choose the appropriate pump from a dropdown of options, screenshot attached.
Note that simply installing one of these pumps and not making the changes will end up setting the car into limp mode (Drivetrain Malfunction) as well as throw various codes for fuel pressure so a map change is required to run them.
For all questions related to the pumps please direct them at TTFS (TuningTechFS) who have done a great deal of work with XDI to make this upgrade happen when it comes to fitment and R&D and they're best to answer any questions. We're simply adding software support for the pumps to make the solution as Plug'n'Play as possible. We have seen a considerable improvement over the stock N55 pump on an M2 while tuning with TTFS end of last year and more recently on an N55 PWG car (both come with the same OEM HPFP pump).
Here's a log of the N55-PWG car running the XDI-35 pump. As you can see there's no pressure drop at the HPFP
