i'm seriously concidering buying this knock gauge on ebay but before i do i want to check with you guys and see if anyone knows anythign about it. he doesn't give a name but it looks ok and he said it works fine. the only thing i'm not sure about is he says once it shows boost the lights stay light for 45 seconds, is that how they all are? i know its not as good as something like scan master or turbo link but its cheap and better than what i have right now, nothing!
