Bummer.
Welcome to ecomodder though.

Im in 2nd by 9mph 3rd by 19mph 4th by 25mph and 5th by 35mph.
That's lower in 4th and 5th than I'd take my 5-speed diesel.
Make sure you aren't lugging the engine.
Low revs are OK, but don't overdo it.
Does the engine still sound happy that low in the rpm range ?

I always coast if I can to stop signs or redlights and anytime that Im able to maintain speed.
Does that also mean you lift off the right foot early enough ?
We use coasting as a (aerodynamic) braking technique, so you have to start way far further out than engine braking (lifting the gas pedal while staying in gear).

If you have to brake, coasting is the best way to do it - more so if you also switch off the engine (which is a step too far for my liking).

I have tried Pulse and Glide but i only see my MPG dropping and never going up. I usually do 10-15mph P&G again accelerating at about 70-80% LOD.
10-15 mph below what your usual speed is, or glides down to 10-15 mph ?

On board displays aren't always correct when you start things like coasting an P&G - what's the situation with actual fill-ups ?

An odd thing that I find is when I drive highway at 55mph I get about 32-38 mpg depending on wind. But in the city im able to bump my trip mpg up to 40+mpg. Why is this. You would think Highway would be better MPG than City
Lower speed - and aerodynamic drag ?

Try the backroads @ lower speed, and see what that gives.

Also Im wondering what PSi I can pump my tires up to.
Mine are at the tyre manufacturer's limits - that's 49-50 psi or thereabout.
Check what the max. pressure is for your tyres.

Anyway, 30 is low.
Winter tyres usually don't help MPG either.
