Default What in the..
hell.. I'm only running 15.5 to 16psi of boost.

Oil temps @ 205-212 deg and water is normal. Car feels slow today and it's like 29F degress outside.
I should be pulling harder! What is this boost retard? This thing is running like *** today!

I have apr's stage 2

Doesn't APR have a specific cold weather update for its chips?

Default I think APR has a different chip for non dbw cars.
That doesn't pull back boost in cold temps. Ask markbradford.

Default That's because....
the ECU is load-based. It does not have a boost sensor, so it adjusts boost levels according to the MAF reading. Colder days have more air density, therefore a higher MAF reading, so the cars run less boost.
