so wait your saying that if you have a scanmater you dont need the gauge for innovate w/b?? because on full throttles website they have the kit that comes with the xd stand alone and 1 universal gauge, but i already have a scanmaster so if i dont need the gauge i could save a little cash. btw i do not have the power logger...is this a good thing to get? is it necessary to have with the innovate w/b?? thanks, Nick
