I read that type of claim a lot (particularly by owners of thirsty vehicles who don't have fuel economy instrumentation), and it never fails to irk me. I'm very glad you've proven yourself wrong!

Obviously I can't verify whether it's the neutral coasting in-town or the coroplast on Highway 45... but something is making a huge difference here!
Going from 11.8 to 15 mpg: the likelihood that the partial belly pan is worth a 27% MPG improvement that you've seen is pretty small. What you're seeing is mostly the result of driving technique.

Don't get me wrong: the mods help, and I'd encourage you to keep going. They all add up. But the biggest returns come from driving technique first -- unless you're willing to completely fair and boat tail that puppy!
