Ok, so I know it's been debated over and over about disconnecting the EGR and how it makes the vanes go into a default that can allow over boosting. So, I've been trying a little experiment.
In my race mode program by Eric at Innovative Diesel (which is usually my DD program), he has it setup to go all out with everything it's got, so my boost will hit 35 to 40 pounds at full throttle. That sounds like they may be at the default position or programmed to be at least.
Now, earlier this week I launched our boat, so I set it down to my Aggressive Tow program since the boat and trailer is only 8500 lbs. I haven't put it back up yet because I want to be ready for the boats first breakdown of the season. Always seems to happen on the Holiday weekends. lol So, I've been driving it with the tow program and I've found that when I hammer it, it won't go over 22 pounds of boost at all.
So, with the EGR MIA and the programming custom done, it seems that the vanes do not go into a default mode and overboost.
Soes that make sense?

Sound like the tuner is cutting the boost back. If you had full boost while towing and hammered it the tires would come loose. In tring to avoid this it's tuned down slightly, gives plenty of power without getting crazy. Try towing with it programed for max performance and just nail it you'll see what I "think" im talking about..
