Why do bigger injectors run hotter while towing?

wonder about a couple things......

I've got 10K on my full meal Fass and I've noticed the pump noise seems to be getting louder. Is this normal? Or is something going wrong?



My pressures haven't changed 21 idle, 19 cruise, 17-18 running hard.



TIA

Probably cold weather.
 
mine is a little louder in cold weather too. What kind of noise is it? Is it the normal hum just louder or grinding or squelling?
