The increased noise is still probably timing related. Without seeing the actual tune though, I can't say for sure. Increasing main injection timing will increase fuel efficiency and power to a point. What often happens is that when the main timing is increased, the pilot injection ( which is timed relative to the main) gets so far out from TDC that it becomes less effective in making the engine run quiet. Often times what guys refer to "injection rattle" on the newer common rails is simply the sound of the combustion event becoming more of a single event vs the normal multiple event with effective pilot. As long as the economy is good, the engine runs good, egts are normal... then no worries. One thing that we must realize is the RaceME probably has all their timing maps maximized for economy. So even though you can change timing, you may only be adjusting max timing... not necessarily the entire timing map from low to high rpm/load.Originally Posted by orlandom
The quick spool setting does clamp down on the turbo control veins at low load/rpm. This in turns drives the turbo harder at idle and makes the whistle. It also allows boost to build very rapidly when you accelerate as well. Technically you are spinning the turbo harder than normal, so yes technically it could wear out faster...but most likely you won't lose the turbo prematurely from running this setting. Soot buildup in the sliding collar inside the turbo will most likely cause trouble before the shaft bearings ever wear out. Soot buildup is something that happens to all VGTs and stock trucks have more trouble than deleted ones.
