Why would Edge Juice with Attitude not work?

No, I was able to read a ECM already tuned with a Predator, and I don't see why you couldn't write to it with the Predator installed already. Do you remember the error code?

I dont remember the error code, but it claimed to have a communication problem and wouldnt load.

What your describing sounds like something was occupying the class 2 data bus. If it has ONSTAR or nav, the fuses for those should be removed before trying to flash it. Also the radio needs to be off if its an 03+ as it uses the class 2 data bus all the time. If the PREDATOR was the source of the problem, you would have gotten an error sayinmg the ECM was locked or unreadable, not a comms issue.

The onstar fuse wasnt pulled... to their memory, but they did try pull the radio fuse/ turn the radio off and that didnt work... Maybe that's all it needed was the onstar business to be doctored

The onstar fuse wasnt pulled...

That's where I would go and then try it again.
