i like my bd and i would never run a bullydog on our diesels. did it once and egt's just skyrocketed.all we run on our diesels our h&S which is the best and smarty . from my experience and the price i tried the bd for my hemi and am happy with it but several people seem to have some issues with em. ive noticed better shifts,throttle response and slight increase in mpg.
