I am here in central Ohio. I know the web page does not have the address, needs to be updated. With the 4 bank you would actually have 4 custom tunes, you are able to turn the chip off with the selector switch....this does not take up a program location. About the multi. program for your car.....since you are adding just gears to your combo now and prospects of a stroker later, I personally would only do the single on the road tune now and have the car dyno tuned when you add cams & such...IMHO
