⦁ Cold Start Delete - All F8x M3/M4s have a cold start calibration to heat up the catalytic converters. If you're unhappy with the way your M3 or M4 idles/runs/sounds while cold please type in into the modification box and we will disable the cold start in your tune. This is highly advised if you are running a cat less exhaust system as the cold start is often very loud.
⦁ Backfire/Burble. This makes your car backfire or burble when you lift off the gas. The aggressiveness can be adjusted depending on what you want. We suggest catless downpipes if you want an aggressive burble / backfire.
