Based off that I'd say my car was 100 at start up, crazy loud for a car at 2k rpm!! Now its about 80. Ill test tomorrow.

PS wife was sleeping first start up and it shook the house, scared her, and she had no idea it was my car or any car based of the type of sound and the volume. She likes it much better now.
