check codes, without them its a shot in the dark. If your charge pipe blew off or cracked youll get boost leak codes, so see what comes up. "limp mode" can be totally harmless if its simply a matter of the engine being too hot, but there are many things that can cause it. I tend to doubt your cp blew off at relatively modest boost, but its absolutely possible.
