Do you have a CAI?
The ECU is compensating for that code, so it's dumping more fuel in fear of stalling out.

Yeah man. I'm getting like 22.8mpg and I drive conservative. I have a ZZP 3" and I'm in need of getting a tune. I'm sick of this ridiculous mpg. I also have an 06.

Reset the ECU. (Disconnect negative cable of battery for like 30 mins)
If you're still getting the code after that, you'll need a tune.
