Just had distributor replaced and timing set to top dead center... after, seems like she bogs more than before... really struggling to gain power till after 3000 rpm... could over tightened tensioner cause this problem?

No. An overtightened tensioner won't cause what you describe. The most common and likely problems are: bad TPS or misaligned TPS, bad airflow meter, improper ignition advance or bad mechanical timing, vacuum leak.
