Is there any item that increases the PP of a move, like the PP-Up and PP-Max?
I need it for 2 moves with low PP.
Naturally none of it's variants either (PP Max).
However, in PMD, IQ Skills are a way of increasing the PP of all the moves of the said Pokemon.
This IQ Skill is called Multitalent, which is found in Groups A, F and Palkia.
Hope I helped!
