I think it's fair I wouldnt either and thank you for the reply.

I thought the predator bloced the ses/cel code from the exhaust like the ppe tuner did. If it doesnt I got misinformed.

I oredered a new one cause I couldnt get a friends U7186 to load into my truck. It was loaded and then unloaded from his old truck but the programmer kept telling us it was not authorized to use in that vehicle. Diablo said to hook it up and call them to tell them what code it gave in the display ...

Would it be better to update after or before programming for the first time? I just ordered mine too.
