Default Tank pressure questions.

I figured I would post this here since a lot of top engine builders and tuners hang out in here.

I saw a pic of Fantini's car from the European championships and he had a high speed needle valve on his pressure line, I would assume to try and adjust tank pressure. My question is, how would one use such a device and why? I am curious since Mugen tanks seem to start out lean when full and richen up as you go. It's not a major problem but if this really would even that out it could provide some performance advantage and I could make one quite easily.

Also, has anyone tried the little Orion pressure regulator? What were the results?

Same question with some answers here:
back pressure effect on performance, mileage, - max power back pressure adjustment
Speed is only fiction but a 130+km/h MRS4 is for real.
