What is a pop and bang remap?

The pops, bangs and crackle mod is also called exhaust crackle deceleration, exhaust popping, burble, car backfire, crackle map, anti-lag system (ALS) or deceleration map. It results in those beastly bangs and healthy gurgles from the exhaust when the accelerator pedal is released.

Pop & bang sounds awesome! You can hear them when you lift off the throttle pedal during, deceleration or braking or when releasing the throttle between shifts. It definitely turns a lot of heads, but it also gives you the feeling of driving a hard core sports car, since these kinds of sounds have usually been reserved for the top notch super cars. Well, now you can have them, too!
It is as simple as that and absolutely beautiful.
How to make exhaust pop and bang?
There are 2 modifications that result in pop bangs.
1. After the throttle pedal is released, the fuel delivery is not cut off immediately. It is delayed in order to provide fuel delivery during deceleration as well.
2. The next modification is a change in ignition timing which we retard. The ignition causing a flame front happens later than usual, thus giving the desired sound. The main advantage is that during deceleration, the delayed combustion flow will also pass the turbocharger causing the turbo to keep its revs high instead of losing revs due to the lack of exhaust flow which would happen without the modification. Aside from the soundtrack benefit, this also means that your car will be faster. This is so because the running turbo means that you waste no time with spooling up when you press the pedal again. The reaction time is noticeably shorter and the turbo lag is virtually non-existent, so we also call this mod anti-lag.
