I installed my JLT II and Evo tune a few nights ago, not only is the power gain great but now I find I get about 2-3 mpg increase on the highway. I use to get about 24.5 mpg at approx 75-80 mph, yesterday I did a 100 mile highway trek and was averaging 28.2-28.6 mpg. Definitely a win-win.
i will second that. i noticed an additional 1-2 mpg with
my jlt2 + 91 tune.
