Re: 2010 pulley upgrade
Which pulley? ie, are you talking about the supercharger pulley or under drive pulleys? From the sounds of your reply, it sounds like you are referring to the supercharger pulley.
THe tuner to go with is whichever one your local shop uses. Some tune only in diablo, some only SCT. They will all do the same thing, so you just want to make sure you get the one that your tuner (the person) is going to tune with.
