I believe that it is really about the understanding of the thought!!
smaller in gears is bigger!! and vise versa!!!
and above all use the calculators not your thoughts of what should be it is how the engineers did it in the first place!!
IT REALLY IS NOT ABOUT YOU BEING RIGHT !!!!!
IT IS ABOUT THE GUY WHO ASKED GETTING THE RIGHT INFORMATION!!!

As for the engineers part, thank you =] I love being a mechanical engineer!

No it won't... To give you an idea of what you're saying... Go get some 5:29's and put them on factory 28's...
Then govern the engine to 3,000rpm... And see where you go...
Diesels have the torque to power through high gears... And that has a two fold effect b/c the red lines are so low on them...
You can not build a Diesel truck like a gas...
And for crying out loud, he basically has an engine weaker than a 20R! And with 1/3 less the rev limit...

It happens, but i agree, the bickering and apparent name calling isnt what YOTATECH is about. I hope it was edited because i can think of at least one member who is younger than 16, and who knows how much younger or looking of a father or mothers shoulders.
eddieleephd, Bantering is alright but if its disagreement with vulgar and attack, i agree it should stop, but we can talk about it, and i agree with your post.
And i think we all agree then, that if he goes with a larger tire IDEALLY a lower gear ration would be needed if he did not do upgrades such as a turbo, intake and exhaust.

But its just not in the yotatech spirit to be like that. And i know of a few young people too. Hell i was 15 when i joined, not that offends me, but it might offend somebody.

and tell me if im wrong, but the gear calculator that you posted if i inputed the right numbers in the right places... says that if no motor upgrades were done and it was left stock that ~4.58 (or 4.56) gears would be needed to keep stock power and the such?

I highlighted the recommended gears

Alright, i do see that now... it does seem odd though on first though... though if i think about it more in relation to tire size and power-band... the power-band has to move when you stick larger tires under there or smaller if you dare wanted to 
But, i trust the calculator at the moment more than my own logic... Cool! i learned something

He said he had 31" and it was already weak which tells me he had like a 28" wheel to start and this is why I say I need the door code to say!!!
just because he has 31"s does not mean they were stock!! with your computations It is assuming this was stock not his last upgrade!!!
We must start with a stock setup then manipulate the rest!!!

First post says he had 31's and 4.56's.
Now, the truck was most likely geared for 31's, it being a non-US truck and a 90's model.
@CsBauer, what i thought most interesting was that the effective ratio was actually lower! At 4.28, too!

What i actually did was a couple different numbers... the 31 he had to the 33 he wants to go to and it gave me 4.85:1 now when i put in a size ~28 it gave me 5.37:1. Now that is assuming he has 4.56 gears. We will have to wait to see what Thrasher says he has since we dont own that truck =[
In all respect i would love that truck... it would be epic win all over the road and off IMO. Then again i just love the sound and torque from diesels

you are right.... and wrong. the OP doesn't want it to be stock, he wants it to be better. regearing to match stock tire size will not make it better, it will still equate to what he is complaining about now. so your right about the gear thing. but wrong about the overall outcome the OP is looking for..

Personally if i was in his position, i would do fuel pump mods, high flow injectors, high flow exhaust, and a turbo. As well as gears for the larger tires.
That way you get all power gain with the larger tires.

So, if he gears to a stock like feel where should he then go. Higher? which i dont think it would, or lower to a more peppy and faster acceleration that he wants or would a turbo and fuel system upgrade help with the need to not gear?
