I'm getting that burning smell above 4k rpms on hard accelerations that everyone says is from overloading your stock cats with too much pressure at once. Not surprised since I'm running a stillen supercharger. It seems as though the smell has gotten more obvious over time though.

Is there anything I can do that's confirmed to help out? Any fuel additives to my gas tank? Run seafoam every 3k?
