I called up a couple of chevy dealers to ask if they could flash my computer going into my car. They said they would have to have my car their for them to flash it. I thought you only needed the vin and the computer to do it.

Some dealers don't have the off board programming harnesses to do it without a car (some have them but have no idea how to use them). You gotta have something to hook it all together when the car isn't there.
We make these for the companies that do mail order tuning. Scroll down to the bottom of this page to see what they look like:

I have a question along the same lines. Can a dealer flash your computer with a program for the hotcam or ASA cam?

I have acces to be able to flash a whole car with a tech 2 but can you use it with the harness from speartech that hooks up to the tech 2. Instead of going to a gm dealership.

No, I don't believe so. Everything is VIN based at the dealer.

If you have the supporting software for factory reflashing, then yes you can do it. I have the GM SPS flashing software here and it's very convenient (but a little expensive for the average guy to have around!).

I have access to the software at the school that I got to "Southern Illinois University" auto program where we have the software. So the harness from you is $125.00

That's correct.
