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 Trailblazer SS

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

Turned a fast truck into an all out beast!

Reviewed By Chad M (Round Rock, TX) Reviewed for a 2008 Chevy Trailblazer —10/16/2011 8:46 PM

Woah!!!! I installed this on my Trailblazer SS. The installation is simple and the directions are very clear and walk you through the few steps that the programmer doesn't do for you (registering programmer, updating, etc). The performance tune brings the engine to life, but the shift pressure was just too much and there rear end couldn't keep up. The 1-2 shift usually resulted in some or a lot of sideways action. The programmer makes it easy to lower the pressure. I also ran the 87 octane tune to see how well it worked. The engine runs fine on 87 octane with this tune, but it definately doesn't have the power of even the stock tune, but it is there if you need to save some money or maybe have a long road trip.
