Modded gxp gas mileage? I really like my folks gxp and have really been thinking of getting one but I don't want to get terrible mileage if I mod it. I get 25 highway with theres hand calculated. If I get one I'm thinking I would do exhaust, tune,and headers was just wondering what you guys get when you baby it, thanks.

Headers are probably the only thing that will hurt mileage, and they're pretty much experimental and very expensive anyway.
I did get a tune to go along with my "modded exhaust" and CAI, and mileage stayed the same. I get about 26-28 on the highway, and don't do any city.

After the mods it seemed like my g-force computer was reading higher numbers then my fuel consumption computer.
I have a 4cyl sunfire for my "daily driver" however my gp is so much more fun and so much nicer to drive I usually say F*** mpg and take it out.
If you want mpg pick up a v6 or I4
If you want a decently quick boat pick up a gxp !

240ish almost all city. 25 mpg... I wouldn't count on it. Some of the mpg claims on here are from "factory freaks" and a good portion of the people will never see that. EPA claims 25 is the max on the highway which means that you will be lucky to see it as the EPA estimates are always optimistic.
