Well, the problen has seemed to disappear on it's own. I haven't heard it in at least 200 miles. Still, the Nissan engineering team is going to check over the car again next Tuesday the 24th. Otherwise the car is fantastic!!! Switching to Mobil 1 on Thurs and on track on Fri!!

 

Glad to hear that RaceBoy, I guess everything fell into place with the mileage you put on it.

 

Raceboy, my noise to is fading fast. At 1200 miles, it's only in 1st & 2nd and very quite. It feels like the car is tightly wound and as it losens up it will handle/drive/speed etc. better.
