I have read a number of threads about the PI being turned off with recent flashes, and threads stating that PI is off from here on out.

I have driven 03 6.0's with pilot turned off and it was rather loud. Are all the new trucks going to be this loud, or is Ford doing something else to quiet the motors?

I guess my question is if I were to order an 04 6.0 now. When it arrived would it be quiet like the motors I drove with PI or loud like the 03's I've driven with the PI turned off?

 

Loud. From everything I read here and on dieselstop, PI is a thing of the past. I haven't read anything indicating when or if it'll ever be back.
