now granted they top out stock at 85(caspers can upgrade to higher), but you can keep your digital dash in your regal or grand national by sending your vss pcm output to the brown wire coming out of your stock speed sensor buffer. then if you have hp tuners or efi live you can set your output pulse per mile to 2000. . i figured i would share as this just saved me an assload of money on a speedo and dash mod.

 

The digital ones also top out at 85, I didn`t know that, that sucks. Is it just the display bars that stop, or do the actual digits also max out at 85?

 

the digits do. apparently caspers will chip them and change it to 135 or so.
