I've noticed the increased performance whenever the temp gets below zero, so I just made my first video of how the truck acts at -20f. I'm running a homemade CAI, gutted manifold cat, and PCMfor less tune. I've added oversize tires, so the speedo is slow, 50 is actually 55, and 70 is actually 77. I was trying to do two runs to 80, but I spotted a cop on the second one. I also have 600lbs of sandbags in the bed, it was too dang cold to take them out. Our windchill is -45f.

Notice how the engine temp drops from just under half to about 1/8 from the cold air through the intake, it also could be from the cold air rushing over the radiator or a combination of both.

When you hit high RPMs the waterpump pressure causes the thermostat to open even if the coolant temperature is low.
