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.

Satisfied

Reviewed By Matthew B (MONTICELLO, IL) Reviewed for a 2015 Chevy Silverado —8/16/2017 5:52 PM

I wanted to clean up my shift points and get rid of the lag when hitting the gas. This thing achieved both those. 2 is what I like best. That's the towing tune. 3&4 are performance and I think they're just to jerky. 1 is just transmission tuning and works great. But 2 is the sweet spot! I also run E85 all the time. Gained 2 mpg also. The only mod I have installed is an Araid mit with drop in filter. Everything else is stock. Am very satisfied with the programmer and glad I got it.
