New update time! About a week ago, I ordered the BBK 66mm throttle body that alot of people on this site swear by. Got it for $190 shipped to my door and immediately put it on. Can't say its a world of difference, but there's definitely a difference! Throttle response is slightly improved and I there seems to be a slight increase at WOT. All in all a very happy investment! And for the first time in the 5ish years I've had the truck, I finally took it to an off-road park. I wasn't really expecting much, from either the park or the truck but they both really surprised me! The park was crazy, even their "easy" trail. Terrible ruts that can swallow a truck up, crazy inclines, creeks and hills and mud galore. It was pretty dry there though so I did have that working for me but further in by the creek had some mud. I really put my new axle set-up to work and can honestly say that my truck kicked butt out there. I may have accidentally went down some more advanced 4X4 courses resulting in some butt-puckering moments but all in all the truck shined through and took whatever beating I took it through. A good 6 hours of wheeling then the 80 mile ride home at 75mph averaging 22 mpg with the AC on. Not bad!
