Continental TSIO-520-R Fuel Flow questions

Hello,

In the Turbo Centurion checklist, the recommended climb power settings are:
  • 30 MAP
  • 2500RPM
  • FF Lean to 120lbs/hr
On a side note, I see that on hot weather the FF may not reach 120lbs/hr with a full rich mixture, therefore you have to turn on the fuel pump to increase FF, then lean to 120lbs/hr.
Why is the temperature affecting FF in this case?

I know that TCM continuous flow system simply delivers a certain amount of fuel given the throttle position. No MAP or other parameters are taken into account.

Is it correct to state that with a TSIO-520-R, the FF will stay constant during a climb and no mixture change is virtually needed with altitude change (given the same MAP/RPM settings) since the turbo will keep the air pressure constant throughout the climb?

Thanks! :-)
