Im new with the Edge Juice w/ *** monitor and in level 5 Its seems almost stock but in level 3 I really feel the power. I ran the without *** monitor for a day or two when I first installed, would this do something or is the engine defueling??

Your tranny is slipping and defueling. Or, you have the max egt set too low and attitude is defueling. I had both occurences on my truck. I set the egt max to 1500 and that stopped the attitude from defueling. However, be prepared, you will be talking to your tranny shop shortly. Personal experience from my wallet.
