@PTF has announced support for @TuningTechFS XDI-35 and XDI-60.
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
