It's the DBW (Drive By Wire) gas pedal (peddle, petal, pettle?) set-up. No cable anymore, it's electronic, resulting in the lag. You get used to it after a while and your foot adjusts to it. There are after-market accessories that claim to fix it, one's called Sprint Booster. I haven't tried them yet and they do cost some money. It's the modern way, welcome to SpaceShip Jeep JK.
Yah, the gas pedal, feels more like pressing on a flower petal; it may be an accommodation to the soccer moms.
