2008 Silverado - Reducing Torque Management

[Mossyoakglock]

When reducing the Torque Management on the GMT-900 trucks with the 4-speed it is not a simple On/Off like the 6-speeds but a range from +20 to -20. Is that +20% and -20% where going more + adds and going more - reduces Torque Management?

And second, do you have to adjust for each gear or for the transmission as a whole (all gears)?
