An SCT chip or Xcal 2 or a Predator. With the 99 an up mustangs, you can only change it with the computer. 98 an below you can use a speedo gear.

Can't you also use a SpeedCal?? I just picked one up for my 98 GT but haven't had a chance to install it yet. I Picked mine up from ebay for a little cheaper than what Brothersperformace sells them for.

You can use a Speed-Cal for 96-04's. They stopped using speedo gears in 95...
