These are the same results I have found as well. Also with boosted cars they are scaled off a lil further then that actually. For whatever reason on the 370's Nissan switched back to a 4 wire wideband which isn't as accurate as a 5 wire in my experience.

That is probably because UPREV does have your ROM converted yet to set up the A/F Sensor scaling in cipher.
As far as the OP goes, I have seen stock Z's dip down that rich close to redline. If interested we offer E tuning and can get you tuned via E tuning and take care of the air fuel issue.
