10,000 miles and getting 12 MPG

[Wildcat]

in my dad f250 KR cc fx4 with 3.73's. What a joke. So much for hidden horsepower too. It looks like im keeping my 06 for a long time!

[_CH_]

but from what ive seen a broke 6.0 will still get the same mpg as a 6.4 thats running well


but im sure there is some HP in there somewhere.... just like the 6.0, just need to get a tuner on it and the CR will be able to pump out some power. of course the MPG will still suck.

Yeah, since SCT is getting ready to release the Xcal2 for the 6.4s, I would get one of those and see what happens. I bet you will be surprised. Also, I am sure there is still a break in period for them, maybe it will get better over time.
