Overrun tuning, commonly known as Pops & Bangs or Crackle Map, modifies the ECU to create a controlled ignition event during deceleration or gear shifts. This results in sharp popping sounds or crackles coming from the exhaust, giving your vehicle a race-inspired presence. Our service is fully customizable, allowing you to control intensity and frequency based on your setup and preferences. Pops & Bangs are available in soft, medium, or aggressive levels, and are only applied where safe — without damaging your engine or exhaust components.
