i have a 98 GMC Sonoma with a 4.6 (V6)and you can hear it grab second gear! but if you dont like the way it set up itself you can go back and customize each and every set up (tire size, gear ratio, rev, speedo, shift fermness and alot more!!) if i was a Kindergarden teacher i would give it a GOLD star!!!

Great Product!!!

Reviewed By Jeff K (STOCKTON, CA) Reviewed for a 2012 GMC Sierra —7/23/2018 9:48 PM

I installed this in my 2012 GMC Sierra with 5.3. I am in California so I was happy this is CARB legal! Install was super simple. I mainly bought it to delete the factory AFM ( active fuel management) which it did, plus soooo much more. My truck runs way smoother on the 87 tune and there is a noticable power gain. Even more on the 91 tune. Firmed up my shifting set at 50%. This is a step above the AFM ONLY delete devices, for not much more cost. Plus you can uninstall tunes and reinstall tunes.
