The first thing I tried when I got this was the Performance Mode (preprogrammed in the Tuner). My only vehicle mods are K&N drop in Airfilter and a Magnaflow Exhaust. The Tuner really brought the engine to life. From the first time I stomped on the gas, the tires barely kept traction and the Trailblazer was off to the races. It really felt like a 5-door Corvette. Next mode I tried was gas saver. Typically I get 12-13 miles per gallon. With gas saver mode, I was able to get 16.5 mpg with city and highway driving. Not too much power loss from stock when in this mode, and I can run 87 Octane! When my wife drives she will get economy mode, and when I drive, Performance mode. I can switch between them in under 3 minutes. This thing kicks Ass! Wish I got it sooner!

Works great. Feels a lil cheesy. The 91 octane tune is great. Couldn't resist the price at auto anything. The time it took to write a tune was about ten minutes. So much more you can do with it. I would recommend it.
