Thats unusual...I can't think of what would cause the trans to not go into second gear. The car goes into 2nd with no problem under normal acceleration?

So what did they do? Change the trans tables? Maybe?

Boy I didn't see that you said the shop used the DS on your current program. If they modified your shift tables like jxaxsxoxn stated they might have changed the kickdown tables. If so it may not have even been intentional. I know when I first tried to mod my shift tables I messed everyting up on the downshit and had close to the same problem.
