It's negligible from what I see. I also drive 50 miles a day to and from work with 75mph speed limits. If I had to put a number to it I have this for you. With the dam the best I got on the 25 mile fuel average was 37 and the was with a tail wind going 63mph. After removing it I've gotten close to that. 36.3 was all I could squeeze out of it. Not too bad. I did the removal that doesn't destroy it. If I ever want to I could put it back on. It's a little tedious if you do it alone but with an extra set of hands I think it would be easier!

I'll have to admit, I have a hard time "believing" the fuel mileage boasts...not sure why, guess the car business has made me a little cynical! Over 12k miles, my truck has averaged 24.1 and since I did the front spring 1.25" spacer at 6k its averaged 23.9. I have a 66 mi round trip, some stop and go traffic and some at 75mph. Ain't no hills in Tampa either!

What Wyo said is 100% accurate.

FL, let the engine break in a little you'll see better mpg. I'm on 2" lift and 32" tires and I can get 31+ Mpg on backroads and <65 highways. At 75mph I'm lucky to pull 24mpg. What a drag. (Pun intended)

He said he has over 12,000 miles on the truck. I think it's broke in. My mpg started going up after 1,000 miles and have been consistent since then and we have 11,500 on ours now. Just saying =)
