TK,
Some things to consider:
Positive caster(top of the steering axis is pointed rearward) aids returnability. It also increases steering effort. I would double check that setting first. If caster checks out ok, here are some other areas that affect steering returnability. Steering column misalignment, column bearings, tie rod end bind, and gear adjustment.
I am assuming your other condition is type of "wander"? Again, extreme negative caster could cause this. Check these factors also: low tire pressure, excessive negative front total toe, brake drag, loose susp/steering components, incorrectly adjusted wheel bearings.
By all accounts, it appears your caster is excessively negative. I'm betting that is the cause of your problems, but I would still examine everything.
As the other gentlemen have stated, look for an alignment shop that understands alignment geometry and theory, not just reading a computer screen. Ask some of the local racers where they go, and follow suit.
Good luck!
Dave
