real quick question. i was real close to buyin the 3.73 gears for my 03 auto the reason i didnt was some 1 told me there was more to it than just buying the gear and it would be around 700$?? something about timing and my spedometer??

yup.

you would need to correct your speedometer as well.

you can buy a speeda cal for around $100
if your car is gear driven (96-98) you can buy a speedo gear instead.. and they are very cheap.

or you can just buy a tuner.

Wrong, the only way you can change your speedometer is through the computer with the tune.

Really? I thought you could speed cal it?

the new edges must be done through the computer... you might be able to have it done at a wheel and tire shop ... but im not sure...

also the $700 part comes in being the T-lok ... or the limited slip rear differential ... GET ONE!! you will not regret it at all ! !

94-98 CANNOT BE TUNED by hand helds for a gear set have to get a speed-o gear or a speed cal

99+ HAVE TO BE TUNED for a gear set no other way period.

your correct.

the speedometer isn't gear driven.
It's electronically driven.
therefore you much go through the computer to correct it unlike the 98-98 mustangs since they were gear driven..

you can EITHER tune it with a speedcal (speedcal is the brand)
OR a hand held tuner such as an xcal or sniper.

so where was I incorrect again?

The 94-98 sixers can't be changed with a tune.

99+ have the option of a tune or a speedcal.

Let me refraise that. Speed cal can only be used 94-04 manual transmission cars and 94-98 automatic transmission cars. If one has a 99+ auto, then it must be done via a tuner.

or a chip

I knew what you meant.
I'm just busting your balls.
