ECS tuning sells them, and claim 7-9hp gains. I am not sure I see how thats going to increase your horsepower, anyone care to try to enlighten me? ;-)<ul><li><a href="http://www.ecstuning.com">http://www.ecstuning.com</a</li></ul>

Default N75 is a selenoid valve for charge pressure control over the turbo wastegate...

...what exactly a <i>racing</i> N75 valve is I don't know.

I know what the valve does... I just don't see how you'd gain horsepower from it...
