404 error!

That'* a good price, but you really want the Pro COMP. It'll do torque, rpms, graph, download to a pc, etc.

I've used both (borrowed the one you linked to, own the better one). BIG difference. Those are harder to use. Not a friendly interface, but it IS the original performance meter.

For me to poop on.

Lol just messin'.
I don't like that uber low price, besides like Bill said its the older one which has much fewer features and was known to be almost impossible to get accurate readings unless you mounted it perfectly.
