My throttle became less linear after the a Cobb ECU tune, meaning the turbo kick in can be felt a lot more noticeable, as well as the lag/bog effect. I have had the car respond in a lazy manner in lower revs before like you described, but I drive a manual, so it's a bit different. If I need to move quickly, I will keep the rev range in powerband, just so I have enough boost through the turbos should I decide to fuck the road in an instant. Have I not done that, and just drove normally in "normal mode" without downshifting, the turbos will need a moment to build boost, the harder you press that throttle the more you'd notice the lag.
