2000 at 70mph and 2300 at 80mph. anybody with big tow notice a drone from their exhaust between 50 and 60mph. sounds like the motor is sluggish to me, maybe I'll go get the timing advance done? I did it on my 04' 2wd KC and it made a nice differance.

I notice a bit of drone at around 1700rpms under load. When it doesnt downshift and you gun it a bit, yeah it feels a bit sluggish to me as well.
