I would love to do EOC coasting but my brakes are powered by the powersteering pump and the auto transmission would be damaged due to lack of lubrication since the pump isn't spinning with the engine off. About the best I can do in that department is Engine On Coasting.

As far as the AFR's are concerned I will be sending the ECU in to get retuned for much leaner AFR's during cruise and shifting earlier under more throttle.

The air dam is currently 9" from the ground so after I lower it will be down to 6". Is it advisable to go lower than that?
