Yea the power is something I got used to very quickly. Can't believe how hard this big truck pulls.

I went with the Hypertech 2000 49 state model on my 2015 Tahoe, I programmed it with the mild tune, and I really like how it changed the throttle mapping. Feels like a different vehicle and runs on 87 octane. No noticeable difference in fuel economy. They should have mapped the throttle like this from the factory! There are other options to recalibrate your speedometer, change shift points and firmness, and a 91 Octane option to add a few HP. I'm glad I got this, the throttle mapping improvement is worth it, by itself.
