just wondering if it is normal what im getting for fuel mileage.
my truck is a 97 f350 4x4 crew cab long bed. engine is all stock. i cut off the cat and muffler and straight piped it but other than that it still has the stock downpipe and all. im pretty sure it has 4.11 because i run right around 2000rpms on the highway at 60mph. it has 35x12.5x16.5 i think that is killing me but looks good.
im getting 12.5 mpgs if i really baby it does this sound right or it is possible i have a problem somewhere truck runs great???
thanks
trent

Unless you get smaller tires you are pretty much there with that gear ratio...You might see a bit of improvement with a better intake setup however....
