these trucks make more then enough hp to pull them down the hwy only thing you are going to see any real differance mpg wise is to clean it up areo dynamicly belly pan lower air dam lower truck remove mud flaps side steps ect base mirrors insted of big towing mirrors. blocking the grill these things will add mpg. the average truck of this size only requires 30hp to cruz at 65 mph. and you are trying to make a giant brick fly

i realize gas prices went up and i feel it as much as the next person but it costs on average 10 dollars a tank more give or take. changing your driving habits is fastest cheapest way to save a buck. if i crawl around in my truck i can get it to 21-22mpg CRAWLING semi's pass me off lights and like others have mentioned cheap beater car costs 1g-2g intake and exhuast costs more and the beater and it will probably get 40mpg+

Programmer coming soon...

I have a level kit, 3'' body lift and 35's on 20'' rim. HWY 15-16+MPG at 50-60 mph any faster and I drop to 13-14 MPG. Couldn't be happier with my gains so far. Can't wait to see what a diablo prediator tuner will do and new plugs, mine are 5yrs old smh...
