So... if my car was EPA tested WITH the shutters and I end up at 34 on AVERAGE instead of the 29-30 I get now, I'd be pleased.

Besides, how do you know it's only going to net 1mpg? Have you done the conversion yourself? I would like to think that the design behind them is capable of more than 1mpg gains over not having them, otherwise there wouldn't be much of a reason to invest in their development and implementation.
Well there's a documented 2mpg gain through the use of the shutters, LRR tires, aero wheel covers, spoiler, and omission of Select Shift. Do you think the shutters are responsible for all of that gain and the rest is a waste? I was merely giving the shutters credit for half that gain, and even that may be being overly generous.
