I have a 2010 Camaro SS w/o RS

I am/have been running the 91 Octane tune on 93 Octane for about a month, although i am happy with it my MPGs are horrid like 13-15 or about 18 at 6th gear cruising at 1500 RPM.

I have resently got a Custom Cat Back with Flowmaster Outlaw Mufflers installed as well as a Cold Air Inductions CAI. I am not sure what is wrong and it seems to be running fine, I was just wondering if there was a way to increase the MPGs and/or get more gains out of what I have done to the car so far. I am very new to this world (of tuning) and I would like to get some answers to basic questions.

Please let me know what to do from here.

yes, there sure is...

you can do some data logging to see where your average long term fuel trims are at, and then adjust the fueling accordingly... that will help with mileage, as well as get you some better throttle response and acceleration...

here's a tutorial on data logging and making the adjustment:
