Air/Fuel Ratio Setting

I have a question about setting the air/fuel ratio at a "safe" setting until I can get my car dyno tuned. I'm sure I can get it adjusted better than where it is now by a little bit and still be playing it safe until I get the car dyno'd. I have a 00 GT 5 spd w/43K on it w/the following bolt on mods: Densecharger CAI, BBK 75mm TB, C&L plenum, Steeda pulleys, Steeda Timing adj.(14*), MAC O/R H-pipe, MAC exhaust, along with the Diablosport Predator tune. I always run Exxon/Amoco 93 octane or Ultra 94 w/Turbo 108 octane boost every tank. Any ideas where I could set the air/fuel ratio to get better performance and still be playing it safe until I get the car dyno'd at the end of this summer? Thanks for your help :hail2:

Originally had it planned for May. Just had a $320 repair bill for my beater car 3 weeks ago. My washing machine at the house just broke, need to get that fixed and recently w/the rain here in PA I have discovered a water leak thru the backdoor/glass in my house. Also i'll be taking a trip to Tx in July... Sooooo, I probably won't be able to afford it until these other things get taken care of. If it's not one thing, it's another. Just some bum luck lately
 
I personally don't think you have anything on the car which would need a dyno tune. Especially with a handheld tuner. Your timing of 14* with 93 octane and octane booster is conservative, and your other mods wouldn't affect your A/F.
