I don't have money for a dyno tune, as I just dropped a ton on purchasing the vehicle several days ago. Any help would be greatly appreciated.

It's mod list:
HTA68 turbo
TurboXS front mount intercooler
TurboXS RFL blow off valve
TurboXS MBC
ACT 6 puck sprung clutch
ACT flywheel
Walbro 255 lph fuel pump

Deatschwerks 750 cc injectors
Invidia cat-back
Invidia up pipe
Invidia catted down pipe
Eibach lowering springs
SPT short ram intake
AEM wide band a/f gauge
Autometer EGT gauge
Autometer boost gauge
Cobb Accessport

I don't care much about power at this point, I just want it to be safe. Thanks very much in advance.
With that many mods, you really should give the car a once-over by an experienced Subaru performance shop. How does the car run in general? How about at WOT? Any hesitation, stumbles, etc.?

What does the AEM gauge read at idle? In closed loop? I would compare the reading at idle/closed loop to the front o2 sensor (which can be viewed/logged via AccessPORT with the A/F Sens 1 Ratio monitor). As SkateAndDestroy mentioned, you can check your long-term fuel trims (A/F Learning 1 A,B,C,D) if you have had a good amount of driving since reflashing a map, resetting ECU or disconnecting the car's battery. Generally speaking, each of these trims should be within +/- 5% or so.
