Hurt my tune or not?? I want to get a cut-out right after my catalaytic converters to have a louder sounding car. Will this effect my a/f ratio at all? And also, if I want to reset my PCM, will I loose my tune??

Don't do the cutout right after the cats. Do the cutout right at the bend before it goes over the rear axle to get a deep resonance in the sound. Or, if you like the rasp, do it after the bend, before it goes into the muffler. Loud either way.
Resetting the PCM will not lose any tunes. A tune is basically re-writing the code in the PCM...therefore it can never be undone unless you get either another tune, or have it flashed by a dealer back to stock.
