Cold Weather interstate boost levels
I just took a quick jaunt down the interstate, to my amazement going up a hill into the wind the boost gauge was reading 15-20psi (50-60% load), going down was 10-15. Does the cold weather screw with the VGT or something? It's about 1 degree outside right now, when it gets REALLY cold like this, the truck exhibits what I would call 'boost creep'. I've also noticed my mileage isn't as good as it used to be in the cold. Thoughts?
