08 Challenger srt8 running LEAN! HELP!!!!!

[rrm84]

I have CAI, Kooks Headers, Corsa Exhaust and have been told by several people that I'm running lean. I've been using the Predator tuner with the Performance 93 Cai Octane tune. When I get to the screen to adjust the fuel which way do I go. To the left or the right. If I'm running lean do I go to 2 % on the lean or rich side of the screen to increase.

Go 10% rich.

How do you know if your running lean? I have an 07 Charger SRT8 with Airaid CAI w/scoop, Oil Catch Can, 180 degree theromstat, stock exhaust with the Performance 93 CAI Octane tune. I have noticed a drop both in performance and mileage within the last couple of months.
