I think I may have fallen victim to this problem. My car only has 1,600 miles, but sometimes when I floor the car, it seems like the supercharger doest not engage right away. I've experienced this while racing several of my friends. I'd punch it and the car just wouldn't go or pull hard like normal. If I stayed in it, as the car sluggishly increased speed, it felt like the charger would kick in a few seconds later???
