Just got my MPVI3 in today. Pretty much what I'm looking to do with the truck is clear some exhaust codes. The truck was deleted and straight piped when I bought it a few years back, but it has recently started saying that the exhaust filter is over limit. What do I need to change in VCM to fix that? I also was looking at tightening the VGT vanes to give the truck more hiss, but I don't see any tables that mention VGT or the vanes. Where would I go to change that?

VGT control is found- Engine>torque management>turbocharger>mono turbo mode/upper limit and the boost control 1-4 tabs. To get the hiss at idle, make sure upper limit table around your idle rpm is high enough to allow what you ask for in the boost control tables. Data in cells are read as a percentage closed. So .90 = 90% closed.
Adjusting the VGT Vanes to Create a Whistling Sound:
Go to Engine > Torque Management > Turbocharger or Boost Control (depending on the ECM).Poor Bunny
Look for tables like Vane Position vs RPM, Desired Boost, or VGT Duty Cycle.
Adjust the vane position at lower speeds to close the vanes more, creating a whistling sound.
