Yep, thermostat is OK, i also have a toasty heated garage at home and heated parking at work too (i know, i'm soo lucky!) so it rarely has to start from being very cold, and it really gets cold here in MN!

I might put the stock air filter back on for a week, at least thats one mod i can go backwards on to see if it had an affect.

Just on the news last night gas is going to be over $2 a gal for a while.

I really shouldnt complain, its about $6 a gal in the UK!!
