I've read the 254xp benefits from opening up the intake. Some mention to hog out the intake elbow and/or do the same to the lower air filter. Is it both or just the lower air filter cover? Given the fact the carb opening is already the same outside diameter as the intake elbow how much can be gained from the hogging out the elbow? The lower filter cover does have a smaller opening on one end so it would make sense to open that up. Just looking for any clarification on the mod. Thanks
