I have another question. My 240v evse is rated at 16a max. If I got an evse that was rated for 240v At 30a would my car charge at the 27a max and nearly twice as fast as the 16a evse?

Yes. Fwiw, I've seen my FFE actually pull 30A but never more than that.

Yes, the FFE has a 6.6kW onboard charger, so if you EVSE can supply 30A (7.2kW) then the car will take the full 6.6kW and charge in almost half the time.

16A@240V = 3.84kW
27.5A@240V = 6.6kW

Maybe Chargepoint is wrong, but it shows that my newly installed home EVSE is pulling 6.98 kW (though it shows 23 miles added in an hour (real time). I thought it peaked at 6.6 kW. I'm running it out of a Nema 6-50 with a 60A breaker.

Its 6.6kW into the battery, there are losses in the EVSE, and the car's internal charger thus it is not uncommon to see rates as high as 7kW.
