It was easy to use I set it up for premium fuel car runs better and I gained about 1 mile to the gallon with mixed driving. I tried to install a jet mass air sensor but it turned on all the dash lights so I had to put the stock one back on then I saw where you can't piggyback with this programmer but I'm totally satisfied with the programmer.
2007 Trailbalzer SS--- Amazing! Works better than anticipated.

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!

I used the express performance tune. It installs quickly and I do notice a harded shift into 2nd gear and more power. It hasn't helped me with fuel economy. I will try the 87 octane tune when I go on a long trip
