That doesn't look terribly dramatic to me.
When you view a log in MegaLogViewer, you can look at the individual modifiers which alter the requested fuel. Collectively, they are represented as the GammaE value. I believe that the one which deals specifically with air density (based on manifold temperature) is expressed as Air_Corr.

Uhm, yeah, I'd say you do.
The difference between 16.2 and 16.5 is so miniscule that I'd typically attribute it to measurement error, particularly in a system which is designed to oscillate under normal conditions.
It's also weirdly lean. Are you trying to hypermile this vehicle?

Yes it only hits that on super low loads, or less than 10% throttle. If i drive it like a normal human being, it'll cruise 15.2-15.5. And when I go WOT, it'll richen up with boost.
So even on the highway cruising 3500 rpm's, I'm at 15.8-16, and if I go to WOT, it'll richen up to 13-12.8 then all the way to 11. Of course just depending on the load.
Just trying to achieve 300 miles to the tank. Since I'm using MS2E from Rev, it's got map switching, when I go road racing, I plan to use the secondary map for more fueling when I'm racing, since MPG's aren't really a concern at that point.

There's a point where too lean is actually less economical than running a fatter AFR. For a time I was trying to cruise 16.2, but I believe I get better miles running 15.5-15.8, and it also seemed to run closer to target more often.
I haven't played with timing much, which I expect is pretty critical when you try to run so lean.

I was around 38mpg with a passenger and a trunk full of stuff. 15.7:1 cruising 65mph, 40psi in the tires. Though, this was my attempt at trying to hypermile it. Oh and i think my timing was somewhere around 36*.
