Thanks and yes it was cool the other night when I went out for a test drive, maybe around 45 degrees out. I do not want to cause any pre-combustion/heat damage and want to get the car tuned properly for all seasons.
My 930 is set up with a K28-11RS turbo with a Kokeln IC. I'm not sure what my air fuel ratio is at this point but will have to find a place in Virginia Beach to check it.
