64 mile commute to work each way. 36 miles country roads, stopping at regularly spaced stop signs every 4 to 5 miles. 26 miles @60 MPH freeway. 65 MPH max. With IAT un-modded, I get the usual MPG and closer reporting of the ScanGaugeII to the actual gallons used. SG reported 9.6 gallons used (35.5 MPG). FE about the same as the last tank, IAT-modded. Proves that at least with my Saturn, tricking the ECU into thinking the engine is breathing hotter air that it actually is, only affects my SG to make me think I'm getting way better FE, until I gas up. SG honest with an un-modded car. Trick it out, and SG tricks the owner!

I think that once the Team Challenge is over that I may return my IAT back to stock to test this on my car. I'm getting great mileage now and I would hate to jeapordize that.
