K&N Air Filter effecting MPG, negatively?

I put in a K&N Air Filter and my MPG has drastically changed. I used to get about 325 - 340 miles to a tank. Now I am getting about 275 at best. Anybody have an experience like this?

panel filter? or cone filter? my panel filter didnt affect my performance, it increased it if anything. have you changed your driving habits at all? (ex - flooring it so you can hear the filter, etc) cuz that happened to my friend, he was wondering why he was draining his gas tank

Most of the time the reason for worse gas mileage with intake or exhaust is just trying to hear it a lot.

its possible, the computer might not have adjusted enough yet, or you might be running more lean with less gas combustion and more of it just being wasted.

This stuff is complicated, read about my emissions problems. There is a number of factors I am am looking over right now. Its a real pain in my ****.
