Not yet Sergiu, but being from Canada it will be colder here soon. You can bet that I'll be sharing that info as soon as I can.
From previous experience working on the ice roads in the arctic with atypical 15/40 there was no discernible difference down to -55*C/-67*F unless the wind was blowing hard enough to stop all work (>35mph), so I'm not expecting to notice much more than a 1 maybe 2 psi increase...
