Filter capacity?

We are currently getting about 100 gpm from our outdoor pool pump. I'm told the pump is capable of much more flow than that. The state regs say our pool should turn over every 6 hours, so that's 167 gpm required for our 60,000 gallon pool. We had the pump checked out and were told the impeller is worn and needs to be replaced.... recommended new impeller, diffuser, and shaft seal. Make sense?
Is there any reason why the flow rate on the pump might be throttled back via some valves in the plumbing system, i.e. to match what the filters can handle? We have 2 Pentair TR-140 sand filters on the system. After backwashing, PSI on filters is usually around 22.
