So I was getting a solid 38mpg, and sometimes 40mpg with stock 2013 Roadster.
I added Ramair, headers, and TOR's and now I really have to baby it to get 30mpg, and typically it's 26 to 28mpg!

Can I do any better?
I realize that to make more HP it takes more gas but this seems pretty extreme to me and would like to know now what is the best I can expect with this combination?
Please list your particular modifications and what MPG you're getting. I think it would be pretty helpful for all of us to know what to expect from different modifications.
Thanks
