Locar kickdown adjustment

Anybody using the locar kickdown setup? I have one and it’s quite nice, but if I adjust like the instructions say the 2-3 shift is late, over 3000 at light throttle pressure. I put about 3/16 slack in the cable and now it shifts normal.
Thoughts on this?
Thanks for looking.

I’ve got slack in mine. Ignored instructions and like others stated get it where you want it. Make sure KD working. If you have a non-stock or modified VB, you’ll have to adjust it some anyway.
