I'm wondering, I have an appointment with Sean in a week or so, I'll have to ask him.. I'm probably going to do the 10lb pully, ****, and possibly injectors/resistor/Voltage Booster as I have the old blue top injectors in my car, first we're going to see if we can't tune it safe at 10psi with the blue top's and water/****.. if it goes lean we're swapping injectors out, I'll probably throw on the 100shot when I get it back too.
