Has anyone ever heard of one of these??

Hypertech TBI Power Chargers (http://store.summitracing.com/partdetail.asp?autofilter=1&part=HYP%2D4001&N=700+ 4294908216+4294908215+4294925008+4294840140+429492 5239+4294848134+115&autoview=sku)

do you think its a good investment or a waste?

I think that's a velocity stack. I am not sure, but I think it is. I put one on my minibike and it seemed to help, but maybe that's because it's such a small engine. I don't know if you'd notice a difference with your engine though.
