it sounds like there may have been something done to your ECM. Are you sure that you are going to the ON position on the key and not accessory (have to ask...Im sure you are since it worked on your buddy's truck). I know with some trucks you have to pull fuzes....do you have onstar??? I don't know if it was an option on your truck.

So, you were able to put your truck back to stock with the predator? try unpluging the edge (it is the inline box right?) and plug your harnesses back in and try again. I don't know much about the edge ez, but I know that edge juice w/ attitude stacks just fine with the predator.

Personally I am using the TST powermax and diablosport predator and it works pretty good. The TST came with my truck, so I haven't decided to get rid of it.
