if you ran too low of an octane the motor could have been detonating, triggering the knock sensor and reducing power. Thats just a thought.
But the seafoam was a good idea, that stuff rocks. You can hook a bottle of it upto a vacuum line that runs to the intake and suck it into the motor that way too, that'll clean up the combustion chambers and intake/exhaust ports of the heads. I'd hook it up after the supercharger somewhere. At the rear IC return inlet maybe.
