Low EGT's. Winter blend or just cooler weather?

I was just noticing that my EGT's where kinda low. I realize that its winter now and temps can get down there but I was wondering if winter blend plays a good part in your EGT's being lower than normal?

Yeah, it's the cold air.

I'm running about 150* cooler EGT's with the outside air in the teens.

I know the winter blend has less BTU's, but your throttle foot compensates for this, which is why less mileage on winter blend. Don't think THIS lowers EGT's.

I've noticed about 2 psi higher boost while highway cruising with winter fuel. Figured it need more air to burn more fuel to go the same distance.

Its not real bad but I can cruise at 70 and EGT's are around 625*-650*. Idle temps are the same.

My EGTs are running lower too.On flat ground, 0 boost, 60mph my EGT is running about 525*. It didn't even get above zero here today.
