Claimed horsepower is not all what its cracked up to be. Just because somebody claims to have the most, 1. Doesnt mean they really make the most. 2. If you have a stock transmission, you really cant use that power anyways. I have run the Edge Juice & Attitude on my LB7, my LLY and now my LBZ and I would not have anything else. I have tried other programmers, and they work ok, but do not offer the convenience, adjustability, and safety features the Edge unit provides.
On this truck, I run the Evolution on level 1, so I can remove the speed limiter. Then adjust up and down with the Juice as I need to. This setup works sweet!
