Everyone can say what they want and even do as they please but 5w30 is a little thick for our cars (my opinion). Also you say you run 93 octane I would assume its tuned for that octane but that doesn't mean the tune isn't adjusting itself. Did you add any other mods since you tuned it. But on the real seams you may need New VVTI cam gears.
