Healthy. Except for your gaps which you say you've already tightened down. Did you regap the factory ones or install new ones? If you haven't installed new ones yet, here's a suggestion:
I'm assuming you're running brand-name regular 87-octane like Shell or Esso/Exxon. Chances are there is at least SOME ethanol in it (likely 10%), plus depending where you are there is the question of the fuel quality itself. Even if you're using other gas, this still applies:
Buy NGK LTR7
IX-11 (stock#6510) plugs. SEVEN
heat range, not six.
Use a proper gapping tool to set them at 0.032" like this:
The short version of your problem: Sounds more and more like the engine management is trying to control elevated cylinder temperatures by dumping fuel and cutting boost.
It isn't really necessary but you can disconnect your battery, wait 10 minutes, turn on ignition, pump brakes, turn off ignition, reconnect battery if you want to REALLY clear your computer (this won't clear the transmission shift strategy though.)
