It sounds like fuel cut to me, but there are easy ways to start eliminating things. I would first start with putting the boost back to stock, especially if you don't have a way of compensating for extra fuel / boost. Do you have a chip, S-AFC, or larger injectors by chance?

If you are still experiencing this problem after going back to stock boost, it wouldn't hurt to through in some new BPR7ES plugs since they are so damn cheap and gap them at .24. If you drive during the winter BPR6ES would work just fine as well. I personally used to change my plugs every 5k miles or 3 months, whatever came first.

Also grab your self some new plug wires while you are at it, best options would be MSD 8.5mm or Taylor 10.2mm wires. Put some petroleum jelly in the boots of the plug wires for optimum performance, this can be found at any local parts store for cheap in little packets, you only need one.
