I just happened to think... don't Supers have all those charcoal canisters and controlled venting of the gas tank? If something is wrong with all that crap, you could be pulling a vacuum on your tank under high flow conditions and that could cause your problem. Try running the car without the gas cap and see if the problem goes away. Seriously.
That's actually a really good idea, Brian. However, I ditched my charcoal can years ago. I do still have the rest of the system in tact under the front hood, so I guess its possible that one or more of the hoses have collapsed or something. If I have any fuel hose left over, I may try the tank vent mod. I've never had an issue before otherwise I probably would have done it already...
