I switch to the 150 tune while pulling my 14,000lb Fifth Wheel, just because I have some mountain driving and the Exhaust temp can get pretty high if you stand on it for awhile in 210. I use the 150 just so I never experience teh dreaded "DE-FULE"! Still happy!

Are you still running the stock exhaust? I get 6mpg pulling and 9 empty.
