I think this is what I'm running right now. Notice how the numbers don't change too drastic like EunosBen's. This will cause smoother fueling, because when you autotune, it's not making a calculation from 14.7-11.8. It's stepping up in fuel in smaller increments. Try mine and see what happens.

It's simliar, but I go leaner in hwy cruise areas...like 15.5-16.0 and not as rich so soon, as it's too easy for me to get into positive pressure with just a little too much throttle going up hills or passing cars or what have you.

I get about 28 mpg after tuning on my attached target. That's just driving back and forth to work and going in boost a few times. When I drove to the Lansdale dyno day in I think it was April? I cruise controlled the turnpike at like 80mph, and I was getting around 31mpg. I bet if I cruised at 65 I'd get better.

Not under full load dummy. It goes open loop if you go WOT at 2500rpm. And 12-12.5:1. Stock, I've recorded as rich as 11.8:1 going slightly uphill on 4th gear. You want 12.5:1 when at ~100kPa. The load is still there.
