i agree w/ tubotime. somthin else might be wrong w/ your rig (he didnt say that, but) i pulled my mom and dads 35' camper and didnt get that bad. and i got the exact truck you do. if your goin for power and economy, take a look at the predator programmer. that thing is just plain neat. i use the 100hp tune alot for cuzin, just for the tree huggers. and the two tune impressed me. it'll really change your truck. for the good.
