I have a bender silencer on my nytro, does anyone recommend getting a power commander or do you think it will be fine?

You won,t know till you ride it. If it hesitates & pops a lot you need more fuel.

My thought would be if you just have the slip on Bender exhaust silencer you'll be ok. That changes if you put on a higher flow header or change your air-box (i.e. - K&N kit) then you'll need the PCIII or risk performance issues or worse engine failures...

I have the Bender on my sled, and with the bottom of the airbox horn removed, I was running lean at WOT. I did have to put the PCIII on it.
