I spent an hour and a half on the phone trying to get this thing to update for my pcm on my 2010 challenger rt. I finally got it working,installed a 91 cai tune,went for a ride,plugged it back in and now its saying it isnt updated again!!!!!!!!!!! What happened? Help!

What is it saying when you plug it in to the vehicle, exactly?

Thanks for sharing such information. I like that keep it up
