Even requesting 300% on KFMIRL, MDMAX 100% and PV"stuff" to 3200mbar will not chance you requesting 2599 on charge... only allow you to pass throught this value on manifold... but n75% will decrease until charge pipe stay near 2599mbar.
There are 2 requested pressure, one from torque path (kfmirl/kfmiop/mdmax) and other from turbo protection, that will limit your pressure on 2599 top
Thanks for reply .
