Sound & Character
Pops & Bangs (Crackle Map)
Add characterful pops, bangs and crackles from your exhaust on lift-off and downshifts, developed safely and custom-tuned to your vehicle.
What is a pops and bangs map?
A pops and bangs remap — also known as a crackle map — changes the way your engine behaves when you lift off the throttle or change down a gear. By carefully adjusting fuelling and ignition timing on the overrun, we create that unburnt-fuel crackle and bang from the exhaust that gives your car a real sense of character and drama.
Every crackle map is written and tested in-house and tailored to your exact vehicle. We tune the intensity to your taste — from a subtle, occasional crackle to a louder, more theatrical soundtrack — and it can be combined with a Stage 1 or Stage 2 remap. As with all our tuning, it's backed by our lifetime software warranty.
What your vehicle needs
To get the most from this remap, your vehicle should have supporting hardware in place. Not sure what you need? Get in touch and we'll advise.
