Tune?
Sorry for the stupid question but I have to know what does someone do when they tune a car. I grew up building engines with carbs and no computers. I have a 93 with the LT1. Is this something I could do or should I take it to a specialist and if so what am I looking at spending.

Tuning a stock LT1 really isn't going to give you much hp/tq. GM did a pretty good job with our stock tunes. But, if you start doing some serious mods heads/cam, supercharger, ect., a tune will be needed to get the most out of your mods.
What can you tune? Click on this link. Then "supported ECM's", $DA2, and "I". It will tell you everthing that is tuneable for your car.

When talking specifically about tuning the air-fuel ratio, you change some table which tells it "given these sensor readings, put in this much fuel."
The basic stuff like fans is trivial. Fuel tuning is a little more involved, but there's nothing particularly hard about it. There's plenty of info on the web for most of it.
For starters, read this and some of the pages linked to from it:

Whether to do it yourself depends on what your plans are. If you just need a couple of things tweaked one time, then it makes sense to pay somebody. If you're going to be modifying and retuning the car incrementally over a long period of time then it will be a lot cheaper to do it yourself.
