Performance enhancements for Z71

So I'm tuning a 2015 Z71.

I disabled the Active Fuel Management

Added PE at 45% throttle VS the 98% that was in there from the factory.

Im pretty new to this ECM/Platform and was wondering if anyone had some tips for bringing this thing out of the dust some.

We drove it and with just these minor changes got some real gains. Drove like a different truck.

I know there are some limiters hiding in here I'm just not sure where to look for them.

I did search the forum a bit. Just didnt find anything.

Thanks
