I agree with you, bigmacdaddy. The wheels lock up at the end of traction. An educated foot might be able to play around on the edges of lockup, but I doubt that the average driver can do that. It seems to me that line pressure is the big factor for lockup. Once again, you may not be able to get there even with boost, but you really don't want to be there anyway.
As to:
'm also still looking for an answer to my previous question about a hidden remote booster/proportioning valve downline from the original Master Cylinder. Any help is greatly appreciated.
I have no idea, but I'll bet that there are several here that do.
