The reason you wont hear the turbo on a 6.5 compared to a PS or cummins is that they boost 18-20 psi, and the 6.5 is only 6-8 psi.<br>the new duramax will be in the 18-20psi range.<br>The 6.5 is a higher compression engine like 21:1 compared to 18:1 on the competition. And they had to run a lower boost so as not to grenade the engine.<br>BTW most pump failures were because of bad lift pumps or PMD failures in the pumps. the pump itself is a good product, most GM dealerships just dont know how to properly trouble shoot problems related to the injection system.<p>Dino<p>----------<br> Professional Ice and Snow Management <br>Products:Services:Equipment
