I'd removed the useless rear spoiler on my SE-R for ~5000 miles, and thought its removal initially improved my fuel economy. I reinstalled the spoiler ~2000 miles before giving it to my daughter's family, and noticed no difference in fuel economy.
California98Civic, Any individual ecomod mentioned in this thread might improve fuel economy 1%-3% at best. That's why none of us shed any tears over their reversal.
