Yep gotta agree. The Edge is a good product all around. The EZ will give you about 60hp with managable EGTs and not much overload on the clutch. You'll probably pick up a couple MPG as well. DiabloSport makes a similar item called the Power Puck. I had one on my '00 and really liked it. Just enough extra power and smoke without much craziness. Got about 20mpg with it in a 4x4 3500. EGTs never got over 1100 and made about 21psi boost.
If you're looking for more power then go with the Juice/Attitude combo or the Edge Comp box. Both are good.
