Sound you get is depemdant a lot on exhaist setup amd if your tirbo or SC.

if you using base B timong all you can rearly do is play arround with the amount of ignition retard you apply and the load\rpm range

lower retard like 0 to -6 generally wont get bangs, higher retard like -16 will get more bangs.

The euro cars that have crackles tuned in likely have specific code in the ecu to create the crackle effect

Run a 2" exhaust from the turbo back. Internal wastegate. Set all ignition tables to -40 to default them to crackle mode. Get an egt gauge. If your EGTs are hitting 1800, you should get crackle noises

So this can't be done at bolt one only

Should be sc or turbos
