I sometimes get this after flashing a new tune.......Ive never seen anything bad from it though

Clear the code and see if it comes back

I believe the U1000 has to do with the PCM's seperate class 2 data link to the BCM. I know I got this code in my swap, but I didn't swap over the BCM. EFILIVE took care of it for me though.
