Power Commander required when Snorkelled?

[whoDEANie]

I've got a set of Performance ATV Snorkels (has dual 1.5" pipes for the intake) on the way for my Grizz and was wondering if I'll also need to invest in a Power Commander? Other than 26" tires, I have no other mods that might affect performance. ...or do I just see how it runs and take it from there?

I guess the question really is: If it runs OK, is there any risk to my machine if it is a little out of tune?

I would try ridding it first and see if you notice a difference, chances are you won't, so I would wait.
