As far as i know there are only 2, Van Akken makes one and the other is the Duramaximizer. All it does is raise your fuel rail pressure, hence giving more hp. As far as stacking with your edge, it will give you more hp, but if hp is the game i think you would be better off getting a programmer or a pcm to stack with your edge. If you go any of these routes, you better pony up for the tranny first, as your gonna kick the sh!t out of a stock ally.
I have a Duramaximizer, I would run a Box/Programmer any day of the week before a pressure box. I only use it for competition. Dynoing, sled pulling, and drag racing. As it makes the engine rattle more and makes the idle kind of funny.
Really? PPE claims it doesn't make any noise different from stock, they claim it as one of their selling features. I'm picking mine up on Saturday, will be stacked with the Juice. If you set the level to 0 does it actually run like stock or does it still increase pressure a bit?
