I'd set the needles back to factory to start with. Could be any number of things

I doubt the roll would cause the needles to move, I've rolled countless times racing. Have you given the truck a good inspection afterwards? Was the body on, or was everything exposed when it happened? Check all your linkages, fuel lines and fuel system for air leaks, check that your air filter didn't get jammed down onto the carb intake restricting flow. Also was the weather the same on both days? Remember nitro motors can be finiky when it comes to temp / humidity changes.
