notice when you take off from a dead stop the power band starts to come in at around 1200 rpms and progressively gets stronger up to a point that point that it peaks which is where the ECM TM is set to reach 100% fueling. because as the rpms and speed climb even if we are at WOT the ecm only allows a small percentage of the fueling we are asking for and then progressively more and more fuel until it gets to the 100% with the smarty settings (higher it shortens the time frame that the ECM takes to get form 20% fueling to 100% so it is mucher quicker to reach the max fueling. I dont know how much TM level 4 leaves in the ECM but if it were to turn it off completely it would be totally in out control WOT is immediate 100% fueling and would roal coal until she got wound up. also part of the reason the "SMOKE SWITCHES" work it is telling the trucks MAP sensor that we are getting more air than we really are and allows for more fuel thus the smoke at lugging conditions until the rpms and airflow actually come up to match the fuel flow the switch told the truck it needed

If the sensitivity (gain) is reduced, and time constant increased slightly, of the fly-by-wire signal, then it will take a much greater pedal stroke to reach 100% throttle in a slightly greater period of time. If the sensitivity (gain) is increased, and time constant decreased slightly, of the fly-by-wire signal, then it will take a much shorter pedal stroke for the same 100% throttle in a slightly shorter period of time. I am almost 100% sure the system gain is linear, or nearly linear in nature, or it would be very difficult to control the vehicle while in traffic - surging and bucking... There may be other variables associated with TM that the driver can't control, but ultimately torque control must be a driver function for reliable vehicle operation.

0 is default 1 is Stock 2 is a little more aggressive then stock (same as Default) 3 is more aggressive 4 is the most aggressive Its the same on Timing, Torque Management, Rail Pressure, and the Turbo. So if your TM is on 4 its going to be the most aggressive fueling at low throttle response. Very simple concept.

Mattpop is right its alway1 mild 4 wild with smarty its just the way we think about the TM that makes it confusing some times. We think of the higher the number the more its adding when with the TM the stock settings are the highest "MANAGMENT" of torque so they restrict it the most, as we dial up the TM numbers 1-2-3-4 we are removing the higher restriction by lessening the "management of or torque" ie releasing the beast that has always been there just held at bay with the factory management restrictions Bottom line is MARCO is a genius and has allowed us to choose the way we want or trucks to respond to our driving habits

Nope I believe he may be slightly wrong....Not that it matters in this discussion, but didnt Marco say that on the vgt settings that 2 is more than 3? I believe this is because vgt 3 was designed for towing because it will not build as much boost as 2 or 4....at least on my truck with ME14

correct for the VGT 2 and 3 are a little different 3 being for towing and 2 being a little more responsive for playing. Not sure why it was set up that way but it is forgot about htat one good catch man

i am with the crowd that believes tm is managing torque sent to the rest of the drivetrain. #1 being stock, may only allow 500ft lbs #2 a bit stronger may allow 650 #3 maybe 800, #4 unlimited. I am just guessing as well, but from what I can wrap my feeble mind around, it is set up in that manner. Obviously I just threw some numbers out, which are of course inaccurate, but that is how I think it is. This would explain how it affects manual and auto trannys in the same way. Once again, this is the shoulders down trying to get in on a shoulders up conversation.
