I understand the fueling box concept, but does the SCT have the ability to switch power settings on the fly without having to re-flash? I have experience with the Edge Evolution, Hypertech and Diablosport tuners for gas trucks. I just like the idea of being able to switch from stock to an additional level of power when needed, but being able to go back to stock output when not needed. One last question....Can the SCT calibrate for larger tires?

Thanks, Nathan
