for a diesel thats a big difference, but ya a gasser not much but might be just enough that when empty you can grab one more gear and get 0.2mpg better milage haha

Even my GM 1500 only drops 200 R's between OD and DOD. Maybe 300 tween 4th at 1.05 and OD at .85. Now 3rd at 1.6 or there about us closer to 600.
At 60 I'm around 1600 in DOD, 1800+ in OD. 2400 in 4th. A bit over 3000 in 3rd
Not bad rpm split IMHO. Be it a gas or diesel. That's 3.42's in pumpkins, 32.5" diam tires.
Not sure what grits issue is.
