you are kinda like asking 'does everyone like ***?'
search the forums. look at the sigs of readers rigs.
better yet, look around at these and other forums (drama stop) and look to see who is selling chips. see how many people are selling jody's tunes. none. hmm....
I really like my programs from Jody (DP Tuner). If you are looking for more power don't forget you need GAUGES because you don't want to melt your pistons.
I've got the gauges, and I have tryed Superchips before, I didn't like having to stop and shut the truck off to switch the power setting. Just trying to get a feel for what is liked and disliked.
