Ok, here it is. Jessee's torque curve in both 3rd (blue) and 4th (red) gear:
If the pattern continues, I bet a 5th gear pull (which due to 4.88 gears, would be similar to a 4th gear pull on stock gears/tires) would result in an even earlier and higher torque peak that has a shape more like Prodigy's results.
I had a conversation with wes today at length. A 5th gear dyno run would bring the truck to like 150 mph. Its out of the question.
4th gear is the closest to 1 to 1 and the axle gear ratio is a non factor.
Its not going to make 40 more hp if you run it in 5th.
