Default RPM with and without MDS

When MDS is engaged or disengaged, what is the RPM when cruising at 65mph on the freeway?

I have an 08 4x4. I have mine tuned with MDS off. Truck is running about 1600 RPM on the freeway at 65mph. I've noticed what might be the MDS drone, but I recently swapped mufflers and it might just be that I am still adjusting to them.

My buddy has an 06 with no MDS and he runs at 2000 RPM at 65 on the freeway.

Could it be that even though I set my Trinity's parameters to shut MDS off, that it is in fact still engaging?
