Power now valve for 450r carb

[PismoLocal]

Has anybody tried using the powernow valve in there 450r carb? Does it provide a noticable gain?

The evidence I've seen shows the Powernow devices give you a modest bump in torque in the midrange at the expense of an equally modest loss on top.

I'd spend MY money on other things but the choice is yours...
