I have a 01 grand am RSM kit, if there is no MAF how do I adjust and tune the Air fuel ratio. Where do I go to change the values, and what values mean what. Is it lower number the richer????

You will need to tune your afr's using your LTFT's and STFT's. Your narrowband sensor is only accurate at stoich, so the adjustments will need to be small.
The adjustments will be made to your VE table (i think others refer to this as SD mode?) for closed loop. Look around for a VE tuning guide (there's one on my website).
For PE, you'll be using the adders under the powerenrichment tab. I'm not sure how others tune for boost here without a MAF.
Since you have heavily modified your GA (ie adding boost), you NEED a wideband controller!!!!! It will make your tuning much easier and much more accurate (and probably avoid an unexpected POP).
