Nothing here ... did you do the install yourself or have a shop do it? Have you reached out to anyone else?

This seems to be happening alot lately. That code just needs to be turned off in the tune.

Why GM put a vacuum warning sensor in the brake booster is beyond me.

Is it throwing the code because it's showing boost instead of vacuum?

i wonder if a guy can coffee can it and check valve it?

It throws the code because it sees a "lack" of vacuum, or in our case boost.

You could run a check valve, but you would need to find a large check valve that is the same size as the factory line.

ill hunt for something, but for now, i unchecked the ses code, and cleared the code.

You can find check valves in that size at any local auto parts store. That should do the trick.
