⦁ 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.

⦁ Fuel - Selectable fuel octane rating (91, 93) 
⦁ Rear O2 Sensor Delete - If you are running aftermarket headers please select O2 Sensor delete. We will remove all coding associated with rear O2 sensors
⦁ SAP (Secondary Air Pump) Delete - If you have deleted your Secondary Air Pump, please select this option and we will remove the coding from the DME/ECU to avoid a CEL.
