Just a hunch, but is your camber on NSF more negative than the OSF, assuming you have standard ball joints?
Before and after the Tyrol Deadset, my car showed -1.5 NSF camber, and -0.85 on the OSF camber - on a VAG Biessbarth rig. According to the operator, he sees that frequently on standard MK5s, let alone modified ones. I was hoping the deadset would level off the camber difference, but it didn't, and funnily enough, my steering wheel was also kicked to the right afterwards as well. But after a lot of fiddling about, we got it all spot on. Initially the camber reference wasn't right because of one side being more negative than the other, so I'm hoping with a pair of SuperPro adjustable BJs to trim the cambers, it should be easier to get the steering wheel straight.
