I have converted my wife's 96 trans am to a slightly unstock ls2 . I can't seem to figure out why I am getting this code . I borrowed the tune from a friend of mines car that is very simular . The p0103 code keeps coming back and the Trans (a4) won't go into lock up ........ any help on this matter would be extremely helpful

You might ask a mod to move this over to the tuning section, you will probably get more help there....

Switch the MAF and see if it goes away. Does it shift okay otherwise just no lockup?

Does your buddy have same stall/trans combo? Many questions to be answered. Most of the time its not as transparent to just switch tunes to another car...

If your buddy's tune is a speed density tune, p0103 will be set. If the pcm picks up any misfires it won't go into lockup.
