Had my blackbear tune and k&n intake kit in my 99 Denali for about 2 months now and finally got it on a road trip to check highway mpg gains along with city mpg gains.
City mpg went from 8 to 11 avg
Highway mpg went from 14 to 17.5 avg
And that's driving with a heavy foot, 190k miles, and the crap ethanol fuel Illinois insists on using.
Even without the mpg gain the blackbear tune is sooo worth it, completely changed how the truck drives, it is much more pleasurable to drive now and the power difference is very notice. My truck doesn't feel like it's struggling at 80mph now and will cruise happily at 90mph if I want it to. That tune is worth twice what it costs.
