don't forget to tune your engine again.. the air in grand junction is probably cooler in the winter and might suggest a re-tune

my buddies sti FMIC is basically touch warm if that on the output side in the winter months, and this is with a massive turbo pushing 300 horse with the wastegate stuck open. you might start getting problems with a lean tune once winter hits

:edit:

on a 30 degree night last winter i touched the FMIC on the outlet side after he was driving for about an hour, it wasn't even warm and he still had the engine running
