NX Plate Kit, anyone using it??

What are the advantages of using this plate kit over a single nozzle kit?

Is anyone here using this kit? If so, how is it working out so far and what ETs are you running? and what shot? How was the install? This will be my first nitrous install.

At what point do you guys recommend getting colder plugs?

Any input would be appreciated. Thanks.

Also if you know a good dyno shop around sacramento or even the bay area I'd like to know.

Thanks guys, has anyone actually used this kit. I know I would prefer it over the zex on reputation alone (not trying to badmouth zex at all), I'm actually considering it for ease of install alone. I just want to know about this kit specifically.
