hcb3200,
Thanks for the advice. I did have the residual valves with the arrows facing away from the MC. That is what the tech support guy from Performance Online confirmed for me. I do think I have a leak but for the life of me I can’t find it. I would think if air could leak in fluid would leak out so i could find it.

I did gravity bleed for about 30 minutes on each wheel. I got bubbles for a long time but they dissipated eventually. I then closed the bleeder. After all 4 wheels were done i pumped the brakes and pedal went to tower floor. If I pump up I get about 1/2 pedal but stopping is not good.

So far I have done a conventional bled with someone in the truck working the pedal. I did a gravity bleed as described and I even bought an inexpensive pneumatic vacuum and essentially power bled them… all resulted in the same squishy pedal. I am going out re plumb the system and omit the residual valves to see what that does. If Im not happy i can always add therm back in.

One issue is I may have created an air trap as i had to go over my drive shaft.I didn't want to go under and I was too impatient to go around it where I should have… live and learn. My haste made significant waste I believe.
