335i N55 What HPFP upgrade should I go with?
So I am looking to upgrade my HPFP. I know there is a few options on the market I am looking for help deciding on what pump to go with.
XDI, Dorch, or Spool?

I am leaning towards XDI or Dorch due to the fact that MHD has options for those pumps already included. If I went with spool would I need to have my
tune file changed?

I plan to do the installation myself self so I am looking for the most plug and play possible. any help would be greatly appreciated.

With out knowing your mods, your build, driving style, end goals, fuel type, etc. ...go for the Spool. Seems legit.

I have a Dorch engineering pump and couldn’t be happier

According to Spool, the Dorch option in MHD will work with their pump. I have the Spool pump but wished I waited for Dorch, it seems like a much better desiged kit with an actual high pressure hard line. The Spool pump also makes a good awful hammering sound through the LP system back into the tank since they remove the damper inside the HPFP. Adding the FuelIt stage 2 LPFP helped a lot with the sound though.
