I recently returned to the stock fuel regulator as well. I didn't seem to have any trouble with fuel pressure and the 255lph pump.
I didn't get to test it very long though, as the motor has now died.

I am starting to think that some returnless fuel system info has worked its way into A9* tuning.



Off Topic -
Since there seems to be a few Cobra tuners here...
Has anyone else had issues with Decel Fuel ShutOff. The car was continuing to run lean several seconds after a shift.
I had to fumble my way through this as I couldn't find any info.
Just curious if other X3Z users have had a similar experience?
