Anyone buy the speed-cal from Brothers Performance

I bought the spped cal and the directions say it can be used with stock gear ratios of 2.73- 3.23. The mach has the 3.55's and Im going to 4.10, what do I do.

I went to their website and used the calculator to get the numbers.

When I was looking for mine, I called them to ask if it would work with a 3650 in a Mach and they told me no

Oops, my bad, I forgot that Dallas Mustang actually makes the Brother's speedcal unit. Go here http://www.dallasmustang.com/index.mvc?Session_ID=5c28a4689abcf0717f6972b4e5cbd 619&s=speedcal&section=techinfo If you are going from 3.55 to 4.10, the code is 1001001111.
