Narrative:

After establishing climb power on thrust rating computer #2 engine failed to provide full rated power. Rough guess engine was providing 70-80 percent of normal power (full flow = 8800 #/hour when other engines = 10500-11000). Engine fuel pressure was normal. We elected to accomplish a precautionary return to mem with #2 engine in idle.
