I have an MPGuino on order, just waiting for it to come in the mail. Still not sure where I am going to install it, but I have a little more time to figure that out. Is it is simple process to fine tune the speed in the MPGuino to the GPS?

On upgrades in lean burn, 32.x mpg up through high 30's. Also true for accelerating pulses on flats.
Downhill coasts in neutral, 200-400 mpg depending on speed.

I guess driving conditions and modifications are too different to really compare things here. With the taller gears I am able to get 32-36 on most upgrades going 58 mph with the rpms right around 1900. I have been lucky enough to stay in lean burn on these same upgrades going 65+ mph, but unsure if the increase in speed combine with lean burn helps or hinders gas mileage. Scan gauge reads it is less efficient as the speed is higher and throttle usage is a little higher than what it would have been at the ideal 58 mph. Hoping the MPGuino will give some insight in which method is better.
So at highway speeds you would not find yourself using lean burn at all on flat or downhill grades because you normally use P&G?
I have also found coasting in gear DFCO does not lower my speed as much with the taller gears. Many downhill grades do not suffer much if at all by doing this.
