My buick cannot hold any boost on the line with slicks. If i use my trans brake my car will hold 20# no problem. I have a art carr converter and all the right parts on the rear brakes. My problem is when i try to build boost the car pushes through the lights. I also have brake pedal that is working fine. I was going to try one of those jumper valves that apply more pressure to the rear wheels.
