Which Octane do you use?
With the SS/SC or SS/TC the typical fuel requirement is 91. Most cars that require premium gas stock from factory are designed for 91 octane. Putting in higher octane does nothing to help performance. Just harder to burn, so thus by using the proper octane not just higher the more effective in HP and MPG the car should be.
I run as close to 91 without going under.
