I might have been one of those unhappy faces but that was because I had mad the mistake stated above. Put the car back to standard configuration & BOOM back to awesome again! I made the setup error & had been awake for 13 hours by the time I ran my final following two 20 hour days before so was unable to concentrate.
No car is going to perform well if the drive is asleep at the sticks
Stick with the suggested configuration and you will have a car that makes you smile every time you run it
