I have the old type ( not selectable) sprint booster on both of my SRT's and never leave home with out them

. You can pull off as easily or violently as you wish with the sprint booster. The trick is in the fine motor skills in that right foot. I would think that most people can master it in a few moments but I have had a few drive my coupe and prove that wrong. You also need to consider the rapid motion of throttle brake throttle in agressive driving when other cars are in close proximity. I think it comes down to personel preference but I sure enjoy that instant throttle on my cars.
