hey i am running a 2.6 pulley on a stock belt and a larger ten pulley. Im not getting any slip or if i am really little but my question is would it be better for a stage 2 belt and a larger ten pulley or would it be too tight

 

I have a 2.7 with a stage 2 belt and a larger tensioner.

 

You are fine. If it doesn't slip, why fix what isn't broken? FWIW, I ran a 2.6 on a larger tensioner and stock belt for 20k+ miles.

For future reference, research everything and ask it all at once before you mod it. There have been many threads lately about your setup, ask it all at once and listen to a knowledgeable member's response. Many on here are incompetent and regurgitate what they heard (usually they mess it up)
