Hey yall.. for those running the N55 motor, TuningTechFS is running a black friday sale on their XDi-35 HPFP. This pump makes a huge difference in heavily tuned motors, supports turbo upgrades and (imho) gets away from what is a questionable OEM pump.
Check it it.. $300 off, running this Friday through midnight black friday. I have a DIY install up for the pump, and is something you can do at home without complicated tools. That will save shop time on the install too.
