Why does my car acceleration hesitate

Genesis (GEN1) seem to have that irritating wait to launch type of acceleration. You may need a pedal commander in which you can control it. I was thinking of investing in one but wondering how long can it last?
My opinion.

My 2015 5.0 Genesis used to have an weird delay in acceleration as well until I installed a Sprint Booster. However, even with the Sprint Booster my Genesis still have a slight delay until about 2000rpm; but the delay was worst without the Sprint Booster.

Hyundai seem to have programed a really delayed pedal response in the throttle-by-wire system to smooth out the ride quality since many Genesis owners probably do not want a twitchy gas pedal or neck breaking starts when they press the gas pedal to go.

Many modern luxury cars seem to have a delayed throttle response until the car is above an certain rpm that can be cured with a throttle booster module like Sprint Booster.
