Narrative:
After departure the right engine fuel flow increased to over 270 pph; the right engine manifold pressure increased off the scale (above 44') and the right oil pressure increased to the red line. I elected to return to the field and had made the decision to shut down the engine in the air. After reducing the throttle to idle for the shutdown there was an audible pop. Immediately the oil pressure and fuel flow returned to normal. I increased the manifold pressure and it responded normally. I returned to the airport to have maintenance inspect. No emergency was declared (although it would have been had I continued the shutdown procedure.)
