first of all, gather some miles on your car. The full power is not available until the car determines it is broken in. Cannot pinpoint it, maybe someone else knows. 5-6k miles? or 3-4? Whichever way, drive! Also, get some SUper Plus or other high octane pump gas. I dunno if your gas card will cover it, but some ESSO have nice 100 Octane gas. If you ever are up in the Baumholder area, look me up and we go driving.
