Wastegate duty cycle

Is there something I?m missing, I?m having trouble with this turbo upgrade over boosting. It seems like the WG duty cycle table doesn?t work. It will all of a sudden command 100% then bang boost spike. How do I command say 20-50% it doesn?t matter what I put in there. The only way I can stop it is to zero out the table or adjust the adder or Multiplier tables but then that up sets the desired boost offset . I?m trying to run 20psi is that to much for the standard set up do we need to go to a eboost?.

You in open loop boost bud

Yep worked it out👍

Standard as in completely standard? Stock actuator spring is 6psi. The best I've gotten out of a BF Mk2 with a down pipe is about 15 psi at 4000RPM tapering to 11 or so at 6000RPM. This is at pretty much 100% WGDC throughout the rev band.
