okay so I have a 2014 mustang gt auto. It has eddlebrock stage 2 supercharger . Car other then that is fairly stock cat back exhaust upgraded spark plugs suspension and in 2 weeks am gonna be getting car tuned with meth injection. I was also wandering would I be able to change pulley size from 3.25-3.0 without doing any other supporting mods ? Like fuel injectors.
