Don't make a mistake, get a stage 2

Reviewed By Robert F (Venice, FL) Reviewed for a 2003 Chevy Trailblazer —10/8/2008 9:32 PM

Almost got a stage 1 but after reading reviews I realized I would not be happy with a stage 1 considering I had a K&N cold air induction and a cat back Flowmaster exhaust, I was right. The stage 2 is what I woul have expected from a stage 1 so get a stage 2 if you want not to be dissappointed.

Computer programmer praise

Reviewed By John L (Puyallup, WA) Reviewed for a 2007 Chevy Trailblazer —4/28/2014 11:06 PM

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.

Reviewed By Donald M (pasadena, CA) Reviewed for a 2007 Chevy Trailblazer —5/15/2012 2:27 PM

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!
