Hello every one i just joined and have a question for you ...I have 410 gears in a 97 cobra and my speedometer is off bad, what do i need to do to fix this problem...

A couple of fixes are available. One the easiest and cheapest fix is
get a SpeedCal unit from Dallas Mustang. Easy to install and works great.
I believe they make one for your year vehicle. Dallas Mustang has a good
website you'll find what you need.

Other options include reprogramming the Computer. This works great but
unless you have access to a programming unit or want to spend $300 bucks.

I'm sure you will get other opinions on this subject. :thumbsup:
