FiTech EFI system
Thought I'd share this little trick mentioned on the Fitech Facebook User's Group. If you are running an external fuel pressure regulator, you can remove and block-off the Fitech supplied one with this BMW piece. I've installed mine already and it's a perfect fit. I'm trying to eliminate the elusive sudden idle go-lean followed by go-super-rich overcompensation issue that others have reported and I think I'm a victim of also. Seems to work so far. I run an Aeromotive boost referenced external FPR. This may not help your current setup or issues, just wanted to mention it.
