Boost pressure variation
Have factory boost pressure regulation with cv and wg. The wg has another spring and is shimmed. Is it possible to get variations in the boost pressure due to different outside temperature? Have noticed slightly higher pressure now when itīs colder outside here .

yes air is more dense when cold and the turbo can run more efficiently allowing for More boost given the same wastegate control design.
The only time this will change is if you are using a MAP based boost controller where it adjusts according to pressure seen at the sensor, and how much it pulses the soleniod.

I am getting about 2psi more boost than from when i set my boost controller a couple weeks ago. It was set at about 13psi @ 70-80*F and tonight i was seeing 15psi @ 45-50*F. It got cold pretty darn quick.
