2018 2ss automatic with dual mode npp exhaust and K&N cold air intake.

When I am cruising around at a steady speed and gently hit the acceleration, the car accelerates smoothly.

However, when I am cruising around at a steady speed and floor it, there is a brief hesitation, I hear a click and then the car moves. At first I though it was the AFM, but when I floored it, the DIC said it was still in V8 mode.
Am I hearing and feeling the dual npp exhaust valves opening?

Lastly: no click heard or hesitation felt when flooring it from a direct stop, which makes me think it is the dual mode npp exhaust valves. Any ideas?
