Well, I'd say only 2. You know when you go into Max Mode, you see hallucinations of things that aren't actually there, like beach balls, and stuff? Either those are part of Max's hive mind or he may have clairovoiance (sp?).
And when Max gets his latent psychic powers, he also had been able to levitate (BTW, wouldn't it be cool if those were one of those playable psychic powers? Like a balloon?). And why was Can 'o Nuts only used in Episode 2? It would be awesome to use them somewhere else.
