Timing and Fuel Air Ratio Question..

I currently have a 5spd 2003 mustang gt with the 2v 4.6L. The only mods I have done to it are a K&N CAI, and a pair of flowmaster 40s. I just purchased an SCT X2 tuner off of ebay, and am unsure of the most effective timing adjustment to make to make the car gain a little bit of power off of 93 octane, and how much to adjust the A/F ratio to compensate and increase the power from the cold air intake. Unfortunately the tuner did not come with any tunes for my car, but I can still makes the timing and A/F adjustments until I take it to a shop to make a tune, but for $150 the tuner was a steal.

Thx

wow thanks for the help, the only thing I've never experienced is when the engine starts pinging, is it pretty obvious when that happens? (amateur question, I know, but I have to start somewhere)
