WoW! I went from 12.5 to 16 in the city, using 91 oct on performance mode, shift points firm. Versus 87 oct in stock.
It's how you drive it that matters. The driving coach is way cool.
And it's fast too!

The tuner works fine on my 5.3L GMC, but I was unable to get the Software to work, even after contacting Edge the maker of this product. I really only wanted to be able to disable the Active Fuel Management, but this unit does so much more.
