I'm thinking about getting cool air intake and maybe a programer.  For fuel economy and to help with my towing.  I tow an open 18' car hauler loaded with atv,motorcycle and a sxs 550 miles one way about 5 times a year.  I'm guessing the load and trailer probably weigh about 5000lbs.  I find that my truck struggles to maintain 65-70 mph.  I get 9 mpg pulling this load.  Would a programer help out?  By the way, I hate check engine lights! lol.  Most of my buddies that have these things also have check engine lights on.....
