When I first installed the tuner, I had some major detonation pinging under full throttle. But after consulting with Hypertech's tech support, they suggested having a shop run some seafoam and/or cleaners through the engine to clean up any carbon on the pistons, etc. My Tahoe nows idles smoother and has plenty of getty-up and most of the pinging went away.

It's works as advertised. Kind of expensive for what it does but , it's cheaper than having a shop do it wrong.
