Burble Tune || EXPLAINED

In this video I talk about and explain how the burble or pops and bangs on deceleration happen and what causes them. Although there are all sorts of ways a car can make the popping or the burble sound happen, the most common cause is the unburnt fuel in the exhaust. I also go over the basics of burble tune and how to tune for burbles on deceleration or over-run.
