MPH increases

[jvmoore]

I know this has been beat to death but what kind of MPG increases can you get with the various box upgrades? I just took a 2000 mile trip pulling a 37 foot, 16000 lb horse trailer and averaged about 9 MPG. I was averaging 11 with my old 95' CTD I also could use a couple of extra HP on the hills

JV, can't help on your question, but that's some trailer you're pulling. 9 doesn't sound too bad for 16k, and if you're running 70mph or so it sounds about right.



Good luck, RJR

try a bullydog powerpup i just put one on mine. havnt towed with it yetbut people are saying like a 2mpg increase with it in tow mode. plus it will give you an extra 50 hp in that mode
