i have heard good things about the diablo and i think the only real advantage superchips has now is the trans tuning. but sometime? hopefully soon superchips will release the vivid/avid that will up the game for everyone with a market share in auto tuners. all i know for sure is stay as far away from hypertech as you can. if you see one free on cl stay away they are a toxic company with shit customer support and care.
