1.5-1.6 bar will be it. I dont have CDB. And wouldnt want to push it any higher than that. And the 1000cc injectors will probably be running out aswell.

Although the DOM 2.5 used to boost creep as much as 1.7bar when racing (from a supposed normal wastegate actuator pressure of 1.4bar) because the internal wastegate valve was an internal wastegate valve.
