on the street, if you build boost and let off on the gas, you'll get the loud pssshhhhh sound! But during WOT, you won't hear anything because we auto's hold boost between shifts. But another use is for burnouts @ the track. Great for putting on a show for the crowd. Plus it's doing its job when I'm on & off the gas trying to heat up the tires. GET IT!
