You're absolutely right. Last week I took mine to the track. The temps dropped into the 50's. The car becomes a beast in these low temps. I screwed up my launch and lost in the first round. But the drive home was more fun than the races!

I deliberately took the long way home and was grinning like a fool at every stop sign and traffic light. The car just seemed to have a ton more power. These cars are temperature sensative to begin with, but after an CAI and a pulley, it is even more noticable.
