Even after checking my pedal and not seeing any flex, I went ahead and added a piece of hard plastic underneath and I definitely saw a difference in throttle response. Anyone not seeing the flex, I recommend trying this fix anyway. Has anyone upgraded their ignition coils? I saw a customer review from an Accel supercoil ignition pac(and wires) on a 2016 saying they noticed better throttle response.

I just noticed that the muffler shop I used for my duals actually went back with smaller diameter exhaust pipes. I have a 2015 Silverado 5.3l, shouldn't I get at least the same size or larger? It sounds great, but every once in a while I have what seems do be some drag when taking off.

It's not loud, but you can hear it. Of course being my truck, I notice it when no one else does. That is a plus though.

Yes, like a helicopter. I may just disable the AFM, thanks.

I just added a Flowmaster 50 HD series muffler and it sounds pretty good. I thought I wanted the 40 series, but the owner of the shop stated people were coming back complaining about the drone. The 50 series does have some drone, but not too noticeable. I also added a CAI for some sound when my foot is heavy.
