I installed this on a 99 Dodge Ram Diesel, The install was fairly easy with the exception of drilling and tapping the exhaust manifold. If you have never done this before I recommend having a mechanic do it or at least watch some instructional videos on youtube. There are quite a few videos that have tutorials on every step of the install. My recommendation is watch the one from Thoroughbred Diesel. The instructions included are great but don't include some of the inside knowledge of a mechanic. Now on to the unit, the five different power settings are awesome, this thing will turn your truck into a beast! Big power gains. Very user friendly and it has a nice big display. I like the fact that it has the port for a back up camera. Makes hooking up a trailer very easy. There is plenty of info and opinions on the various web forums out there. I highly recommend that if you have a second generation cummins to upgrade your lift pump, the factory lift pump doesn't supply enough fuel for this mod. A larger exhaust is also recommended as well. Bottom line is the Edge Juice with Attitude CTS is a cost effective upgrade for any vehicle.
