True, unless possibly the mods increase the VE of the motor and you get some mpg gains through greater efficiency. We'll never know if the mods or the tune are what increases mpg since so few people are going to spend the coin to tune a bone stock car. Plus it all goes out the window when you put your foot into it anyway.

Next best way would be to make sure your tires are properly inflated.
Last would be to do some weight reduction.
