Great product guys!! thanks
I'll have to go on the forums and let all those guys running those no name brand tuners whats up!!!

OKAY, I have to retract that last post. I'm pretty sure that you are right 06MonteSS. I just confirmed with my buddy and it wasn't in the on position.... " FUCK" ... sorry guys... I'll let you know when its on.

Thanks for the reply. The ignition key was in the "on" position, not turned on or running. That's the situation we're in. Its pretty weird, don't know if this is common. But yes that would be a probable cause if that was the situation.

Just purchased the predator U7191 for my '06 AWD trailblazer SS at Mopac autosupply in Langley B.C. , and it would not download. I took all the precautions like removing the onstar, and radio fuses, turned off all electronics. We plugged it in, it asked me if I had an automatic trans. clicked yes ...
