sup. and to answer your question in the chat box, your the 05 gt is not supercharged. the 04 and 05 still used the gtp name for s/c option and in 06 the s/c option became a gt. if your dealer said it was id be raising hell about now. UNLESS... you bought it used and you happened to get a gt that someone had put a supercharger on afterwords. basically if you can take a pic of your engine bay i can tell you.
