start up and lack of idle

Hello, I have a 98 LS1 with Prc 2.5 heads. A texas speed Magic Stick 3 cam and a fast 102 intake and TB. For the life of me I cant get this thing to start. Im having a issue with the TB relearn. I did it a few times, successfully. But now, it wont relearn? Also, I cant seem to figure out how to get her to run. I have talked to a few folks around and they gave me some ideas. Its just not wanting to stay running. Heres my tune and last attempt to start her. Any advice would be greatly appreciated
