If you are having problems like this then you are settings somethng incorrectly, as the gm is far more efficient at adding timing than the tekin is. Brakes are also a non issue as I, like others have no problems locking the brakes up. It would also be more effective for you to ask for settings or post your settings for us to look at rather than just coming on and complaining. What surface are you racing on? What is the ambient temperature? How big is the track? all useful information for us to know if we are to help you
