First of all, Thanks to all that offered their helping advice. I ended up having to get a custom tune. During that tune, I learned gobs of information about my truck/LS motor. During the tune, I learned that the passenger o2 sensor was not functioning properly. I also learned that i had a small exhaust leak on that same side that was actually throwing the os sensor readings off. The tuner really knew his stuff, unfortunately what he ended up doing was turning my 02 sensors off, then tuning it. He has scheduled a return to properly tune it when I fix the exhaust leak.

Different subject, if my 1980 truck did not come with a power brake booster, how difficult will it be to integrate one. Will it help me? The autozone master cylinder that is on it can seem to stop leaking fluid.
