Haven't really got into tuning this platform yet, but your long term fuel trims are probably close to maxed out. That means the computer is adding fuel to compensate for more than expected air, and can't add anymore. Possibly some kind of vacuum leak is causing this.

What programmer/software did you pull that data from?
