RowdyRebel Posted July 16, 2016 Author Share Posted July 16, 2016 Moved a horse to another pasture today and figured I'd snap a pic. Looks pretty darned good, if I do say so myself! Stopped on a fairly steep gravel incline and started easing into the throttle...about 1600 RPM she started moving forward. Pulls pretty effortlessly, but then again it was just around the farm so I didn't really get much speed built up. 2 Quote When approaching a 4-way stop, the vehicle with the biggest tires has the right of way!

RowdyRebel Posted July 19, 2016 Author Share Posted July 19, 2016 Well, it got us to Nashville & back without any trouble. Cruise set @ 73 most of the way made the trip go by pretty quick. Got 10 mpg on the trip which was a little disappointing...going to have to get with the chip programmer and see if we can't do some fine tuning to get that up a bit. It COULD also be that it's a brand new engine...Mack got a new one of those in December and it was sucking down fuel for the first few months before the mpg's started going up. So, we'll wait & see...but I still plan on seeing if the guy down there in Millington has a Dyno and would be willing to tune in-person if I ran it down there one of these days. Kinda slow returning to idle when you rev it up, and it still feels a hair light in the power dept. We'll see....
