ambient temp/boost pressure question >
 

about how much drop in bosst - if any - should I expect between an ambient temp of 100 and an ambient of 60, about 2psi? I run 21psi max at high temps, about 19.5 at 60. Normal, I guess?

The ecu tends to dial it back when it gets colder...
 

if you have a boost machine you can crank it back up.

oh, so it's not a direct relationship with ambient temp - the ecu gets involved >
 

I do have a boost machine, btw, and have heard about seasonal adjustments, but just thought higher temps equaled higher pressures, without the ecu.
