ALH TDI went out of time when my belt tensioner went bad. Belt and tensioner were replaced. Car starts fine but runs like it did when it jumped time. What did I miss?

What do you mean "runs like it did when it jumped time", how did it run? Poorly?

Did the camshaft go far out of time? Did you check that there was no valve-piston contact?
