It’s a 96 7.3 f250 1 ton, I hear the engine ok but next to other truck same kind of year or at least body type it seems way to noisy it has a strait 3 in pipe no silencer and a intake the cheap one the “napa” any help on diagnostics or enlightening me thanks

 

Non -factory intakes are much louder.

 

the noise its not the turbo whistle im referring to its the engine noise that distinguish diesel engines its louder

 

I was not referring to turbo whistle.

 

a faulty icp or ipr can do this and the computer strategy can make a difference

 

sorry but could you explain whats the "ICP" or "IPR"
and what do you mean by computer strategy changing it or what
thanks

ICP is injection control pressure

IPR Is injection pressure regulator
