I thought the jet sound was supposed to be the SAP. If you don't have SES light, then you likely don't have any significant vacuum leaks. At least not enough to justify 15 mpg. Though you live in Hawaii. I can't imagine driving there is very efficient.

I have a dream that one day our children will live in a
nation where they will not be judged by the color of
their skin but by the color of their coolant.
