Mental Intrusion (Ex)
At 2nd level, as long as you maintain psionic focus, increase the save DC of any mind-affecting power you manifest by 1 for every 2 power points you spend augmenting the power, provided the augmentation does not already increase the power’s save DC. For the purpose of this ability, you may spend additional power points augmenting a mind-affecting power’s save DC even on a power that normally does not have any augment options.
Endowed Mind
As long as you maintain psionic focus, increase the save DC of any power you manifest by 1 for every 2 power points you spend augmenting the power, provided the augmentation does not already increase the power’s save DC. You may even spend 2 power points to increase a power’s save DC even if the power does not have any augment options.
Do these stack? Would a mind-affecting power increase its DC by 2 for every 2 PP spent to augment? Mental Intrusion is Extraordinary and Endowed Mind is Supernatural.

No.
Imagine a power; we'll call it basic power. Let it be a mind-affecting power. That power does not have written into it that it may be augmented.
You are a 10th-level manifester and basic power is a 1st-level power.
Thus, you can spend one power point to manifest basic power. End of story.
Now, with either Mental Intrusion or Endowed Mind, you may increase the DC by 1 by spending 2 additional power points. Each of those two options specifically say "provided the augmentation does not already increase the power’s save DC".
So if you spend 3 power points on basic power using Mental Intrusion to increase its DC, you cannot use Endowed Mind because that 2 power point augmentation already increases the power's save DC. So for each power point you could pick one or the other of the two abilities allowing the augment, but not both.
