I have heard so much about turbo timers and the actual need to use a TT, the thing ive heard the most is that new cars dont need more than 30 seconds to cool down so a turbo timer is totally worthless.... is this true? and what are your oppinions on the HKS turbo timers? Also correct me if im wrong but does a turbo timer not make your car easy to steal?

Thanks
