temperature and humidity. it can change it a lot. that's all I can say. someone that has a manual installed will have to give you more info. i am just repeating stuff I have read in previous posts.

Colder temps = more boost. As the temperature of a gas decreases, the number of molecules per given volume increases.

Due to our freaky weather, we deal with this A LOT in Colorado. It could be 70 when you roll into work & drop to 30 by lunch. Change is good. :)

The spring in the MBC is affected by temperatures and can change the boost as well

I think the reason most MBCs' calibration varies with temperature is what 91White-T said. Air density shouldn't affect the pressure differential on both sides of the valve.
