Are these worth a darn?

Just curious, not buying...

Btw, I should say I'm interested in the "Instantly change your power curve and shift points" part, not the over-rev part...

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.
