Found this today and sounds like someone got the facts mixed up, DMAX was first with quieter engine.

1) Maintenance Safety Tips for GM's New Duramax Diesel Engine vs Ford's Power Stroke </TD></TR>
<TD class=verdana vAlign=top bgColor=#fceeeb>
<TD class=verdana width=580>Situation
<LI>Ford's Power Stroke diesel engine fuel injection spray pressure runs from 3,500-21,000 psi
<LI>Duramax diesel fuel system takes new approach to high-pressure fuel and lube oil spray
<LI>Jacks pressure up continuously w/ special pump and control injection w/ special module, high voltage and electronic injectors
<LI>Duramax ECM programmed to operate injectors in 2-stages like Power Stroke 6L to reduce noise and emissions
<LI>Common rails mounted externally on Duramax while under valve covers or cast into cylinder head in Power Stroke </LI>[/list]</TD>

</CENTER></TD></TR></T></T></TABLE>Significant Points
<LI>Extreme caution must be exercised in dealing w/ Duramax fuel system and high-voltage electrical system
<LI>Maximum control oil pressure on a Power Stroke nearly 4,000 psi, Duramax fuel system is pressure-relieved at a blistering 27,550 psi
<LI>93-volt high-voltage Duramax wiring harness must be replaced rather than repaired
<LI>Fuel rail pressure (FRP) sensor must be replaced if ever removed due to high damage probability </LI>[/list]Read Background
