Speedcal Question

[Shiroelex]

I've been driving around with the new gears without a speedcal installed, and I'm tired of not knowing how fast I'm actually going. I have a few questions for those of you with the speedcal.

What ratios does it support? I heard that it only goes up to 4.30, which wouldn't do me any good.

Where and how does it install?

And the last question...
If you had stock gears, and set the speedcal to if you had like 5.13s, that would make your odometer turn less than the actual mileage that was being put on the car?

go to the dallas mustang website...they have a forum dedicated to the speedcal. Lots of info to read through.

The Dallas Mustang Speedcal appears to support the 4.56 gear ratio. Also, it's very easy to install. It has a connection to the transmission harness and that's about it. I have mine slid up in front of my gear shifter under the dash.

If you are getting a Speedcal get the one from Dallas Mustang.I know
the guy that makes them for Dallas Mustang and he does a great job and knows his stuff. I have heard that Brothers Performance got a bad batch
of Speedcal's and people started returning them and complaining that they
didn't work correctly.I installed my Dallas Mustang Speedcal in 30 min. tops
it's really easy to install.Just follow the directions it's easy.
