Thanks Lonnie.
PS I was just thinking (dangerous I know). I would need to set it on both ends
so do you think there would there be any issues with different MTU's at each
end?
Ultimately it would be the same eventually but there would be a migration
period.

I haven't seen any issues with a WG MTU of 1340, yet anyway.

they use Carrier Grade NAT (CGNAT) for IPv4 which lowers the MTU to 1420 (just
like WG) so WG needs a MTU setting of 1340 to work over the CGNAT or else it
hangs.
