I jus got a diablo i3 tuner for my 2013 suburban and I'm aware they're multiple tuning options for transmission shifting, tire size, gear ratio, and so forth. But when using the diablo i3 tuner to change the tire size, does that automatically change the shift patterns to compensate how hard you are applying the throttle? Or does it literally jus change the tire size to show you the right speed?
