Im looking into geting the tuning manual from sct. I think its about 75.00 from lethal performance. Is it worth it?? and does anyone have one already. The (how to's and help tabs) on the pro racer program are ok but not really any help. I hope it is because ive been emailing sct about the school they have for the dealers to go to and ask about an individual attending and have yet to hear back from them. So anyone that has one please leave some feedback!!
