Spends too much time on here
I've already said it twice...eTorque is responsible for your increase MPG's in the city. Ram claims that eTorque gets 2 MPG better economy in the city than a standard Hemi.Then why am I at 18mpg and you at 16mpg?
I didn't say you made a negative comment about etorque, I said I've repeatedly read that here; not that the opinion of those making the comment matters to me, just pointing out the seemingly prevailing thought here about etorque.
Secondly, your chart or premise seems wrong, my truck (presumably all the 3.21 trucks too) doesn't even go into 8th until 54 mph. Using your steady speed of 35mph and my above chart, the 3.21 truck could be in either 6th or 7th, lets use your 7th gear reference, at around 900 rpm to make 35 mph. The 3.92 truck is at 1000 rpm is at 32 mph and would likely be at ~1100rpm to make 35 mph. That's a 300 rpm difference.
There's nothing wrong with the chart. You're interpreting it wrong, because it says nothing of the sort. Your chart is unnecessarily complicated. The TCM will not allow you to drop below ~1100 RPM's under a load, therefore you will be in 6th gear at 35 MPH and 1183 RPM's. I will be in 7th gear at 1213 RPM's. I just checked the accuracy of the chart I posted and it's spot on for 35 and 45 MPH. I also checked to see if I could hold 8th gear at 968 RPM's at 35 MPH...it won't.
