4.2 GAME CHANGER

Reviewed By Linda R (Titus, AL) Reviewed for a 2008 Chevy Trailblazer —10/19/2017 4:11 PM

Jet seems to be the only programmer that works for the 4.2 chevy inline 6. No problem with the installation and I noticed an instant increase in the low end power. this is where the 4.2 really sucks. Don't know why they did not use the 4.3.

2007 Trailblazer SS

Reviewed By David P (Aurora, IL) Reviewed for a 2007 Chevy Trailblazer —12/14/2011 11:58 AM

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
