Problem when boosting on a new 6 bolt swap with DSMlink?

[4twenty]

Whenever the car hits boost it pulls timing. This is a 6 bolt in a 97 gst with dsmlink. I haven't checked for knock yet but what else could pull the timing under boost? I was also wondering if it could be a bad cas? Car runs and idles fine but after you boost it floods the engine , pulls timing, and it is hard to start for a minute, because of the flooding. I am going to do some more logs today but any ideas?
Thanks

maybe a little time spent on tuning.

I don't think it has to do with tuning, the car is only making 6psi before the problem or sometimes it will hit 15 and then timing drops. All fuel and timing controls are at 0 in dsmlink right now.
