This is interesting I did a simular test on intake piping for my car. Also I seem to notice that either my car is flowing alot of air or maybe there is something weird about my MAF. On average I can pull 4.64-4.68v from the maf but when the temp drops below 60*F or at nite sometimes I peak between 4.69-4.71v. So far I have cai, PS header, phenos, 2.25in catback w 2k maxima muffler, UR UDP, JWT s3's/ecu.
Where did you install the wideband, I'm assuming that an extra bung was welded to the header for the o2 right? If I could free up some power with a nismo FPR I would definitly go for.

Hotshots intake had the highest MAF voltages, but didnt make any more power on engines that are cammed out and less midrange than the PR. Well I put my wideband A/F meter on a friends car and found that the HS runs on the lean side and the MAF doesnt compensate entirely for the gains in flow. The HS was putting out 4.56 volts at the fuel cut, a lot for just a bolt on motor with S4's.
