I geared it (4.10) for future 37" tires a few months ago while I installed Air Lockers. So I have been slightly over geared the past few months. Based on the online calculators, I should be just about the factory RPM range as a stock Rubicon Diesel. At 70 MPH, I am at just about 1900 RPMs.
How are you liking the diesel + auto combination?
Any thoughts on getting it tuned with someone like Green Diesel Engineering?
What mileage are you getting these days?
Thanks,
-Dan
