I have an 86 Ram with a 318 and it has a lot of performance issues.

#1 - It missing a little under load despite a full tune up and a sound engine.

#2 - It seems to have the feeling a trans issues like it almost feels like it kicks down but the trans is sound and recently overhauled.

#3 - It lacks power even for an 86 2bbl.

First should I ditch the logic module/computer and go with an aftermarket carb and ignition? how did I work the lock up converter if I do? Or could I have things like the EGR opening at the wrong time or a vacuum issue?
Any help would be appreciated. The truck only has 60k on it but was sitting a while before I started driving it.
