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.....
