hey bro looks sick see u around here and rkc

should sound like this you should also remove that car they run better with nothing

its called compression surge..... thats your problem with a bigger intake the turbo sucks more air in , and upon deceleration it pushes the remaining air out causeing it to hiss as the turbo spins the oposite direction
