In my wife's PT Cruiser - the RPM drop VERY VERY slowly.
like over a 3 minute period they drop.
I was trying to gather data on coasting in gear compared to coasting in N and i noted the RPM did not drop.
Since i have the SG hooked up, i could see the MPG increase in both cases.

After playing with it some more - I have chalked it up to ECU Programming to try to decrease delta in engine RPM and transmission RPM.
