Fuel Mileage questions I know I know!!

[StrokerTurbo7.3]

I'm using what I think is stock, lol. that 200 was as of last saturday. I'm now wondering if my econo tune is in the right position, because it seems like I get worse mileage in that tune than any.

Is call Tony and findout whats what or even send it in and get it re-vised.

I have the list of what was burned on it, in the order that it was supposed to be burned, but it got me thinking, how do we as a consumer really know what is in what position, hi idle is a given though, lol.
