Do I need to reprogram my computer?
Little info ,1994 corvette automatic , So far I've installed 2600 vigilante converter, 3:07 rear gears , exotic muscle headers with corsa exhaust and high flow cats . At what point do I need to reprogram the computer other than just for the speedometer ?

You could honestly do a tune anytime you want, even on a completely stock engine. For what you have you don't necessarily need a tune other than maybe getting the speedo corrected from going to 3.07 gears. I think PCM for less will only charge $50 for a second tune if you ever added more down the road. Something to think about.

As noted above, you can have a tune done anytime to dial in the small changes that were made. The computer will compensate for your changes without too much of an issue.
You will positively need a tune if you change the cam to one that is different from the stock cam.

A custom tune for your engine will always extract the maximum.
I tuned a stock 86 with great results.
Later on with a few other changes the next tune was most impressive.
Find a good tuner now before you start making changes.
