I think I will try some simple aero mods instead of messing with the turbo anymore. What it is is what it is. I get around 36.5mpg. These are 'real' numbers. My drive is 50 miles one way and back everyday with minimal stop signs. No high speed driving, 60mph. top speed.

I would suggest not altering your boost management system.
And coasting in neutral usually isn't good for automatics.
Turbos don't suck down energy like more rpm does generally. Its like engine displacement on demand. And with a 1.4l you're going to want that baby snail pumping air... that's what it was designed for. To cruise with a 1.4l and accelerate with like a 2.5l.
But messing with a turbos hardware and not tuning for it can cause engine failure.
