Higher fuel pressure from scan
My remote tuner has looked at my data logged files as below
"The log file shows what looks to be more fuel than is generally needed across the board, however the underlying data commanding that fuel looks to be accurate. This suggests to me that you may have slightly higher fuel pressure than expected/specification "
If I do have a higher fuel pressure, can that be tuned adjusted? or do I need to change the fuel regulator . I have no idea where this would be on a 2007 A6.. One for each tank?? I can't find any parts numbers for these or any information

I would get a decent mechanical fuel pressure tester and check fuel pressure at your fuel rail.
The fuel system isn’t easy to work on, and unless there’s a real problem verified by your mechanical gauge I would hope he could adjust the tune across the board, isn’t that what tuning is?

Yeah, that's my next plan. My mechanic guy in the UK doesn't have the correct fitting for the fuel rail yet but when it arrives I'll check out the pressure .. I also thought the fuel should be able to be tuned out as well. Thanks for your input
