Before range tech using quart oil 700 miles now zero. I am very pleased. Rate it a 10 plus. All ready told people about it.

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.
