the 266G/sec is the max number on the Uprev table. the way it was explained to me in the beginning was that as long as you can give fuel with the MAF Table the G/sec is kind of useless

this is a copy/paste of one of my concern on this topic with Jared @ Uprev

I don't think I've ever seen the g/sec go down while the V was rising, but I honestly don't usually look at the g/sec since that parameter becomes totally meaningless once you change the K fuel multiplier for a different MAF or injectors.
Groovy.

Yeah I need to start logging manifold pressure, sounds like.

don't lose your time with the OEM MAP sensor on the 370z.

it will be better with an actual gauge that can read vacuum properly.
