4.10 gear

VanHall · April 29th, 2007, 02:02 PM

I have a 02 mustang if i get a 4.10 gear is it going to mess up my milage at alll until i get a tuner

DrHolliday · April 29th, 2007, 02:18 PM

yup, I drove mine for 2 days without changing the gear tune.

Speedo said 28 and I was really doin about 20-22

when it said 85 i was doin more like 70. Hope that helps!

well i have gps that will tell the speed
but does it mess up my milage and also do i have to
buy a tuner to get that fixed and if so what is the best one
that will increase my acceleration

DrHolliday · April 29th, 2007, 02:26 PM

My fuel mileage staid about the same, 20-22 mpg. You shouldn't need a tuner for more acceleration. The engine will run the same, the gears just get you into your power band faster.

But a tuner will give you 10-20 hp depending on what other mods you have.

o ok i heard that putting in a gear can mess up ur actually milage like miles u put on a car

and whats better to get for speeed a chip or tuner

and since the tuner doesnt give u more accleration what is the purpose of it ?>

Drgnracin72 · April 29th, 2007, 02:33 PM

yes with bigger gears, it will add miels to your car that you never drove. you need to change that with a tuenr

DrHolliday · April 29th, 2007, 02:34 PM

You will get more power and in turn get more acceleration. but not as much from the tuner as you will from the gears.

And yes, If you don't have your cars speedo recalibrated your mileage readings will read more then what your are really going. I'd go for the tuner b/c you can change things when you want. With a chip you would need a new chip to change things like gears, tire sizes. and any other little things.

VanHall · April 29th, 2007, 02:36 PM

thats what i thought so i shoulddnt get the gears without the tuner
what about when u get the shop to install it do they do that for you
and with a tuner can u adjust things to make ur car quicker

My gears go in tommorow and then i go to ford on tues to get them to flash the computer.

ujslost · April 29th, 2007, 04:43 PM

you can buy a speed cal if ya want

zkid01 · April 29th, 2007, 04:58 PM

There are a few ways you can go about this.. getting a tuner is the best! But you can get gears with a speed cal it will be cheaper, but the speed cal wont help anything else.. You can get the gears and after they are installed, a ford dealership can hook up there computer and change the gears..
Like they said above if you don't get it calibrated it will mess with your mileage. And your speedo will be off.
I would suggest if you are getting gears get a tuner (diablo or xcal2) that way you get a little more HP and you can adjust the gearing yourself. Good Luck.

VanHall · April 29th, 2007, 09:21 PM

is it hard to adjust wouyld i be able to use it myselfd and if i get a 4 10 u think that would be the best one for it and how much will they both cost toghther do you think.. and will that tuner take carf of the milage and allow me to adjust acceleration and power or no

zkid01 · April 29th, 2007, 09:48 PM

americanmuscle.com has a gear/tuner combo pack you can get and save a few bucks.. Yes it will fix your speedo.. and mileage.. and give you some more power.. And as long as you can follow directions you can do it yourself.
