DP Tunes and that ^$&%! Diamond Eye 4" Exhaust
Put both DP tuner (Econo, trailer, 100hp) and 4" Diamond Eye exhaust on early 99 to help with economy.
May I be roasted in hell if ever I get another Diamond Eye exhaust! 8 HOURS to install - nothing fit - turbo flange 1/8" too large diameter, and way too thick: 2 hours grinding it down. Pipes not angled correctly - now am baking my spare tire. Sheeeeesh!!!!!!
However, DP tuner makes truck much more drivable! Love it - well worth the $$.
Have not seen any improvment in MPG tho driving very conservatively. But, except for the memories of the &#&$& exhaust install, love the truck now!
Any more 'improvements' ideas, that don't involve living under the truck to install, that may help MPG??
