Okay... engine lugging is bad, this I already know. What I don't know is what exactly (or close anyway) constitutes lugging? When I shift into 3rd at 8mph and the tach drops to 650rpm in a no load situation? When I accelerate (unloaded) gradually in 5th from 1000rpm? I don't want to hurt the truck, but I LOVE
low end torque! Help me out here guys...
Thanks,
Adam
