Keeps popping up. Just installed a silver 64 and CTS is still reading boost so I assume my MAP sensor is still ok. Trucks locked out of TC lock-up until I clear the code, but doesn't last anytime at all before its back in "limp"

Just puzzled why it'd be tellin me under boost condition. About 500 miles on this turbo and its just showing up. I'll check the map sensor connections for the juice w/attitude when I stop.

Did you find anything when you checked the sensor? Make sure to insure you don't have any boost leaks anywhere next time you stop. (put some of the windshield cleaning water all over your boost tubes or find some soapy water)

I've been told this code happens often... mine has done it maybe 5 times in 4 years, always while on the highway but it resets after I pull over and doesn't come back.

I'm running a silver 64 with a CTS juice w/attitude as well. I'm wondering if it is possibly a software issue with Edge? Did you delete the factory electronic waste gate?
