SCREAMNEAGLE, the EZ box is made by Edge products. TST makes the Powermax 1,2 and 3. They also make the Powermax 3 adjustable. The EZ is plug and play. The Powermax requires that you tap into a wire on the VP44 fuel pump. The EZ box is a minor fueling device while the Powermax, at least the PM3, is a major fueling device. I would suggest getting in at least the EGT gauge before you install either box, or any other for that matter. Put the thermocouple in pre-turbo (exhaust manifold) as you plan to Bomb your truck. Then I would add the EZ box. I did this to my ETH and I think you will be real happy with this simple upgrade, plenty of power and it won't be too hard on your clutch. If you went directly to the Powermax or any other major fueling box, the clutch's live will be very short. Hope this helps. Forgot to add... the EZ is adjustable in terms of when the fuel is added in relationship to boost. There is a jumper setting inside the box that allows you to adapt the box to your needs. Setting one (most aggressive, and, I believe the way box ships from Edge) worked real well with my then otherwise stock ETH.
