What turbocharger are you running? There is a point we're the additional psi gains from the standard turbo are outweighed by other factors but you should be able to push it up to 22psi comfortably.

So I contacted them and unfortunately

"Thanks for your enquiry. Unfortunately we have made every effort to create a throttle controller that operated within the correct parameters for the Discovery 2 TD5, however we have not had any luck this far."
