Regeared to 4.10s on Tuesday (7/17/18) and put 500 miles on before this weekend's prerun for next months offroad event. Unfortunately, due to the new gears I was forced to tune the truck as cruise control did not work... Long story short, I purchased a Diablo I3 and uploaded a custom tune yesterday.
Along with shift points, gear ratio, tire size, etc, I adjusted the radiator fans due to my over heating transmission. Its now setup to run the fans considerably more once temps are above 210 and 100% after 225. After testing this in the mountains today, I'm happy to report it made a significant difference in temps.
While I had gotten to 250 twice before, I stayed under 220 95% of the time while creeping up over 230 once during some more "spirited" driving haha.
Regarding the bumper, it should be going on this upcoming weekend!
