I needed to use EA's charge station near my apartment the other day. They have the 'up to 150kw' and 'up to 350kw', I know that the MME is only supposed to be able to handle 150, normally I pull 125/130. When I plugged in to the 350kw charger, I was surprised that the charger stated my car was requesting 167kw. I did notice a whine that I hadn't noticed before, and it did slow down the charge rate after about 8 minutes. And yes, I get it, the car will pull as much as it thinks it can handle. I'm thinking they (ford) are holding out on us.

Yes, it is requesting ~167 kW at some points at 350 kW chargers.
No, it will not be able to request significantly more because we have 400V battery.

I think I saw that on my recent road trip but I don't remember for sure.

They should rate them in current and not kW. It is misleading. The 150kW chargers can do 350A maximum which is 133kW @ 380V (80% Mach E SoC). The 350kW chargers can do 450A so 171kW @380V if the Mach E requested that much current. The ratings are charger max voltage times charger max current. Assuming the charger is providing maximum current you'll have a lower possible kW at lower SoC. For example a 50kW DCFC that is 125A will see a max of 47.5kW at 80% SoC on the Mach E. Misleading rating them in kW.... Since the EA chargers can do 800v systems they can rate that crazy kW number even though the current is the same no matter the voltage.

The whine you hear is the charging cable cooling running.

Edit: I think my current numbers are correct but someone correct me if I'm wrong. I can't find the specs sheet I read before and was doing it from memory.

I try and use the 350kwh machines because of the higher initial charge I am receiving. It seems to charge a bit faster than the 150kwh machines.

Of course, there's a better than 50% I'm full of crap too ?‍♂

It does because it is current limited below 150kW at the max voltage that the MME can take.
