Well, not getting ping at 16 psi, no IC huh? Does it make power? or is it just not moving enough air? Mine pings with 15psi spike and 300cc injectors I am moving some serious air though.
Anyway, newer wheels are just so much more effiecient due to lighter and less blades on the wheel.
O, I got a Fidanza and I like mine. The thickness is about same as stock one but it weights only half of the stock one. Plus, it's got a replaceable center contact section.
