2016 Camaro, custom comp cam with a comp limiter. I can't get the cam timing operate at low retard. I can set the vvt tables to just 1 at 5000 rpm. When it hits 5000 rpm, the duty cycle on the phaser (can't find a cam position pid) goes from 0% to 50% and I get a huge dip in power. Its like its going from 0 to the full 22 degrees the limiter allows. I cut the ramp rates for the vvt in half to maybe slow down the commanded duty cycle and no change.
