You are probably running real lean if you where tuned in missouri High altitude and the cold.
Take it easy on the car until you get back to conditions the car is tuned for.

Actually a tuned car, taken from low elevation to high elevation is going to be rich . The thinner air up high will show less boost as well.

Can you smell fuel or a real rich exhaust odor ? Wonder if it's trying to flood it self at idle?
