my first question is is the engine calibration in the stage 1 kit the same as the stage 2 kit? my second question is is the stock supercharger hub going to work any other pully size. cuz the stage 2 kit comes with a hub? so im confused if i need that hub from the stage 2 kit or not. also i wanted to install the 76mm pully instead of the 78mm pully that comes in the stage 2 kit. which hub do i need for the 76mm pully
