I'm grateful that my dad had walk 4 miles to school UPHILL BOTH WAYS, every day. Now that I live on top of that hill he spent all those years walking up, I'm okay with my 3.21s. Every drive is downhill... Thanks, Pops!

It definitely does the job for most people

Something I think I may have noticed - how many of the 3.21 drivers also feel the need for a pedal commander? :unsure: Is there a cause and effect relationship? ;)

Hey, I don’t have a pedal commander, so don’t think there is a relationship.

Something I have noticed, that 3.92 drivers shave their bodies, oil up and wear tights. I don’t need to know why.

Strange

I have one but after messing with it a bit I pretty much settled on one of the lower settings which is very close to stock throttle response. I have since removed it and seems my truck has greatly improved since brand new. I have zero complaints right now.

I have not noticed that. Schick would have to ramp up capacity, and the only time I get oiled is changing the filter. That's probably too physical for 3.21 drivers. And I don't imagine even 3.21 truck drivers in tights, that sounds more like Formula 1 style.

I feel it's strange that you are looking at other guys oiling their bodies while wearing tights. And you don't even care why they do it

Nope. Two completely different things.
 
Supposedly Truck Trend did a test in 2019 on nearly 2 identical ram 1500 trucks.
One was 3.21 and the other 3.92. (Saw some references but could not find actual TT article.

0-60 mph - 3.21 wins slightly
1/4 mile - 3.21 wins slightly with time and speed

0-60 mph (towing 7500lbs) - 3.92 wins slightly
1/4 mile (towing 7500lbs) - 3.92 wins slightly
