Gear ratio for 35'' tires

[mino_h]

Does anybody regeared from 3.73 to 4.10 with 35'' tires or bigger tires? Does the swap is worth? on the gear ratio chart shows that 4.11 or 4.30 is the best for fuel economy for 35'' tires. I want to get back my MPG ... any comments or suggestions?

I'm running 3.73's no problems here 20 MPG hand calculated and figuring in my 10% loss

Get a chip from Tony Wildman..you will see mpg add of 1-2 plus HP. Gears will not gain back your mileage
And get rid of the K&N before you loose your turbo and motor!

if its the full K&N with intake tube and all, its fine. If its just the K&N filter drop in for the stock airbox, get rid of it. Unless you're going bigger than 37", no need to regear. The price you pay for the gear changes is gonna be quite a bit of diesel fuel, and for 1-2mpg(MAYBE) difference, its really not worth it.

35"s with 3.73s is fine, just get a chip to make up for the power loss....

And definitely lose the K&N....K&N drop ins are ok, their full intakes are known for dusting turbos....Ive had an interesting experience.....

Negative Blizzard the drop in K&N's are the worst thing you can put in a truck

Ive had K&N drop ins on 3 of my trucks including this one....Within 2 weeks of me switching to the full intake, I lost my turbo....Drop ins are fine with me. Ask around, there are plenty of people on here running drop in K&Ns without any problems....

i got an idea
lose the k&n filter and put a 6637 on the end and everyone will be happy!

I currently have the ford AIS intake, and I love it.
