Tom-what do you file your ring end-end gap to on the top two rings for boosted applications?
I would check that tune good it could be part of the issue

As for the rings .004 to .0045 x bore on the top ring and .005 to .0055 on the second ring x bore depending on what level of boost and performance and its very important to have the ring square with the deck , you can use one of the old pistons with all but the second ring off to pust the rings square in the bore , some know this but adding it for others that dont
