i have Efi Live and DSP5. it is all in the tuning. one can make bad tunes and the transmission will have a hard time adjusting to it. if the tuner knows what he is doing then the relearning of the transmission is seamless and quick.
i make my own tunes and the relearn between tunes is done within a few miles and some of the tunes you can hardly tell.
the throttle and torque tables play a large part in the adaptability of the transmission.
