Aftermarket CDI boxes...

I have a Vortex ignition, paid $250 I think...???

Did it make a big difference?

Worth $250? $100?

I guess I'm really interested in the bottom end difference aspect of it.

I thought my CDI was bad, hence the replacement. I did several changes at once: 420 kit, re-jetted AGAIN, and the Vortex.
