Just got my 4.10s installed and they fuggin rock. I got a Dallas speedcal in to correct the speedo but its still 10 miles per hour off. I am thinking that maybe someone put in the wrong speedo gear. Anyone know if could possiblely correct the speedo so it reads exact speed.
I original had 3.27s in the rear and it was 20 miles per hour faster then what I was doing. I am thinking that their might be a 3.55 speedo gear in it. Any insight is appreciated.



4.10s FUGGING ROCK

 

Yeah, just keep playing with the dip switches.. look at the chart and make sure your going left to right... It should have been closer if it had the 3.55 gear in it.. mine went from 14mph off to about 8mph off with the 23 tooth... just keep trying different combo's till you get it right.

 

it doesnt matter, you could shoot a 5 hour video of you driving around and show it fulling up and some retard will still say they suck on the highway and you get crappy milage

 

Ill let you know how it does on milage when I go to fill it up.

 

Mileage isn`t that bad. You might lose 1 or 2 mpg depending how you drive.

 

this is why everyone is so gay..

its all about how you drive

sure, if you knew a guy who knew a friend who had 4.10's and he got terrible mileage cause he hammered it ALL THE TIME, then everyone keeps spreading the same damn rumors

enjoy man, i love mine thus far

 

Who cares about mileage, its a Mustang...not a Civic. I get ****ty gas mileage and I don't care because I bought a MustangGT because its a v8 and I love Mustangs and its fun to drive. I drive around half throttling it alot and not shifting until 3-3.5k but I don't care about the gas. If I wanted good gas mileage I would have kept my civic. lol

 

I have to care about milage just a little bit, because I unfortunely must deliver in the mustang, not that its a bad thing or something. Most of my races I rarely get into happen while I am working.

 

Oh I see. That kinda sucks having to use your nice car to deliver stuff.

 

what do you have to deliver? one time I had to pick up 4 tires in my car, it was so gay. I was pissed too
