I'm HUNGRY for more power! From what I've read it is safe to run a 75 shot without any tuning or colder plugs... I live in Ca and 91 octane is all that is available at the pumps, I have a custom dyno tune, I don't know if the timing is advanced with it, if so can I still run it? If not, is the 91 cai tune safe to run with a 75 shot? Also, I have a manual 6 speed so is it safe to run a WOT switch or do I need a window switch, I love burnouts and dropping gears and putting the hammer down!
