Can u keep a Sprint Booster on?

I just purchased a sprint booster for my audi a4 to help it jump faster at lights, but I love driving with it on 24/7. It has three modes no light is factory (off), green light is improved response smoother driving, and finally red light is improved response agressive driving. Is it fine to drive with it on the red light (aggresive driving) 24/7?does it do any damage at all? I don't wanna mess up the ECU or anything but I just love when its on that mode lol
