gas mileage improvements
 

I think it would be a great benefit if there was a table generated with the car name , changes made, the good and bad found out, and what did the person learn

Matt?
 

This would be quite the project unless there was a way we could enter the data into a web form individually.

Matt -- is this do-able/feasable?

If not, then the FAQ section of busted/confirmed mods would be the next best bet. The Gaslog also could be a good place to look as it has comments on mods performed and the actual data, but rarely an A-B-A test. Just click on the car of interest and dig into the logs...
