    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.

    Finally!!!

    Reviewed By Colin A (League City, TX) Reviewed for a 2015 Chevy Silverado —10/14/2017 3:30 PM

    This little device saved my truck. I was COMPLETELY dissatisfied with the easy the truck ran when the AFM system kicked in. Now, I feel like I'm actually driving a TRUCK!!! As far as gas mileage is concerned, I didn't buy a V8 truck to get good gas mileage, so not worried about that. I will say, though, I haven't noticed much of a decrease.
