2013 FX4 SCab... The All Terrain Good Year Wranglers (18" LT) couldn't make that huge of a difference could it? I mean people are running 20" LT Nitto Trail Grapplers and getting what I'm getting.
It's possible, but mine has the 20" wheels with factory Bridgestone tires and it does get better than the 16mpg average you're seeing. My 2012 had 18's (can't remember the tires it had) and got pretty much the same as my 2013 does; both have/had 3.73 gearing. What was your plug gap at? .030 - .032?
Yeah I've driven quite a few EBs and they do pull hard. But I love hearing my motor and the EB doesn't really have anything to make the exhaust sound good. But spool is nice. It's so hard to find a 6.2 truck
Agree that none of the aftermarket exhaust do much for the sound on the EB, though the Full-Race exhaust sounds decent, but not like a V8. I do love the look on peoples faces though when they try to overtake me from a stop and my 3 ton silent sled blows by them
