Gentlemen, first of all, thanks very much for the input. It is greatly appreciated.
After driving the car about a hundred miles since the tune I'd like to more fully describe the symptoms. When I am cruising out of boost, it drives fine. When I begin to get into boost, usually starting at about 2900rpm + or - 300rpm, it feels like I've hit a flat spot. The car stumbles along as the boost levels are between 1 and 10 psi. Once boost goes above 10psi, she pulls hard. This whole issue is particularly annoying because during casual driving, the car wants to be in the 2600-3600 rpm range making low boost levels which is exactly where the problem is. To drive the car smoothly now, I need to avoid boost or get deep into it.
I will investigate the BPV (bypass/recirculating valve) possibility. I'll check for leaks and I've got a few spares on the shelf.
