What does buying the SD 1 bar do over not using it?

After I finish tunning the LTFT/STFT's.

I should set the parimeters back, After that to turn the Check engine light off for the MAF failure, should I just set the low/high MAF frequency to 2- No MIL light?

After this is done am I am officially SD tuned?

I have searched but yet to find a good write up about SD tuning. If you have one in your favorites can you please post.

I appreciate it.
