the only reason you would want to get the car scanned before doing the mods that you listed is to scan for dtc's....That goes for any car just to make sure the car is mechenicly sound before you start modding it.If your cel light is not on your not going to come up with anything anyway.as long as the above conditions arent present you will be fine doing the mods you mentioned....the main thing people scan for when they say there ''scanning'' is for kr (knock retard) all the above mods you are doing will be helping get rid of kr not increase it vs. putting a smaller sc pulley on your car(then you would want to scan and make sure you have the supporting mods first
