You can light the tires up, it just has a lag from when you give the command and when it carries it out. When I'm at a light and I wanna get a jump on the green, I kinda hit the gas a second before I want to actually start moving. It's not your car, it's a drive by wire issue that a lot of cars suffer from. the old days when you had a cable, even slightly resting your foot on the gas made your rev's blip. Now there's a threshold you have to pass before the car realizes oh, he wants to go. That instantaneous response is a thing of the past. And all a SB does is make it feel like there is another foot pressing on your foot.
