Great Product!!!

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.

Picked this up after reading some good things about it in GMC forums. I've never used a tuner before, but this one was pretty easy to use. I stayed with the a canned tune with no modifications, but the difference is easy to feel. Especially improved is the tune for the transmission. No more waiting for the trans to decide what gear it wants to be in. Shifts are firm and immediate. Highly recommended.
