One major benefit on the two trucks and one car I have installed front air dams (chin spoilers) to is the decreased buffeting during heavy cross winds on the highway.

I believe in all three cases hwy mph went up about 1.5 mph.

However, there are several reported cases in the forum of decreased mpg with the use of large chin spoilers/air-dams.
