Is a CDI worth it?

I have someone wanting to trade my a new in the box cdi stage 3 by dynatech. I just dont know if it would binafit me any? I do most of my riding like you guys in the woods at a slower speed. I only go fast on the roads to get to the trails. I just did not think it would binifit me that much. Just thought I would get some of you thoughts on it. Thanks Tim

It benfited me esp getting rid of the reverse rev limiter and seemed to give it a little more pep

I dont know on a 660. but on a 700. it made quite
a difference.....

On a 660 it makes a BIG difference!!!!!!!!!! Never heard of a stage-3 tho???

Pate with your new setup. its going to be
like a stage 8 , ant it.......

Stage 3 bumps up the RMP limiter a little higher than stage 2. I have read that the stage 3 are mostly for built motors. It seems there are lots of folks running the stage 3 with stock motors here and on other UTV sites And IMO its worth it just for the reverse limiter being eliminated. 10 extra MPH dont hurt either.
