Certainly give it some time to make sure you're OAR has had time to adjust. I'm looking forward to seeing how it does on the track.well, debated posting but I am going to any ways..... the GH tunes are in and I am not overly impressed at all..... Its not much more of a difference over the stock tune actually... although the Trans performance is greatly improved, it drives nice and the truck has no lag, which is better than the stock tune and the turn around/customer service was amazing, as always.
I unloaded the GH tune and did some hits with stock tune... did the same with loaded GH tunes again.... I will say it is stronger than stock.... but not what I would have expected given my 2015 and how it ran..... I guess the track will be the true sign....... will get there in the next couple of weeks
