2 psi residual valve.

Do you have enough pressure going to them through the proportioning valve? Might dial it up and do some lockup testing.

Mine was lifting until I opened the prop valve more and then it started to pull the rear down slightly. Front to rear pad compounds are your other tuning tool. Run a caliper pressure calc to determine if you need different or matched pads front vs rear. I'm running a less aggressive pad in the rear to balance caliper force.

My visual impression was your rear brakes were on the smallish side, so I'm GUESSING the fronts may be overpowering them.

Are you running the factory delay valve? You could remove that, though mine seems to work fine with the delay valve.
