Proportional Brake Bias

I am installing a lever style proportional brake bias valve in my IT7 car. Should I remove the stock proportional valve?
Thanks

you don't have to, but you can. works either way. i think i have a little more control without it.

Consensus here is to remove http://www.rx7club.com/showthread.ph...ght=brake+bias

I removed the stock one on my 2nd Gen and found a good balance with 2 clicks up with the Tilton lever.

Thank both of you very much.
