Yep!! A whole bunch use them, except me

! It will help with your shifting and some with the thinking, but not the spinning wheels part. I would not think anyway. ATX's are prone to looseing a great deal of power through the drivetrain. Most everyone that has a chip, in one form or another, with an ATX has been happy. Not cured, just happy.
And if I am not mistaken, most around here use the SuperChip. I don't see too many with the Diablo, but they seem to be happy too.
