How can aircraft engine response rate be adjusted?

Hello All. How can engine spool up and spool down rate be increased? I fly Kirk Ollsons excellent P-3C and the problem that I have not been able to overcome is the very slow rate at which the engines respond to throttle inputs.The lag is 7-10 seconds from throttle advancement or retardation until the engines reach the desired setting. And it makes small throttle corrections very difficult to set accurately. Fuel flow changes end up being the leading indicator that a power adjustment has been made.Thanks in advance. Rick
