Cold boost

Does anyone else experience higher boost when it's freezing and if so how much, like 1 1/2 lb when it's real cold
Cheers

Due to cold denser air will improve turbo but I have never really looked at the gauge as in psi amount. Cold air coming into intercooler Is good.

I do tend to see an increase in boost when air is colder.

It's more noticeable the other way around though - when it's hotter there is less boost.
