Proper air to fuel ratio.

Proper air to fuel ratio.
I got my dyno sheet out today and noticed that my air to fuel ratio is 11.3:1. Every thing that i've read says it should be like 11.8-12.0:1. I called the guy that tuned the car and he says he did it to be on the safe side in case i got some bad fuel, but is'nt that a lot of hp left in the car? I run 94 octane and 10.5 lbs of boost on a gsr. He says i could probly get more power out of it by leaning it out, but he doesn't suggest it. I thought that 12:1 was safe, and 11:1 would almost be flooding it. Does anyone have an opinion or experience with what it should be? Should i have him lean it out, or just leave it?

RE: Proper air to fuel ratio.
It depends on what you wanna do.......you wont get THAT much more power out of it ,so why not stay safe........what are the specs on youre injectors/fuel pump etc fuel system stuff.
