I have a 2004 cobra and want to put smaller pulleys onand i dont know if my car has been programmed or not. It does not have the factory pulley on it I know for sure but I dont know if has been programmed for the smaller pulley, (ie 2.8"). I believe it is the 3.4" or the 3.1" but dont know for sure.Does anybody know how to check if your car has a programmer on it or not? thanks

 

not sure that there is a way with out having a system to plug in to check.
