Is the performance gauges option worth it? Or is it better to just get the boost gauge? Is the boost gauge necessary, would it be better to get an after market one? Also anyone got any pictures of the fog light kit?

no. way way way over priced. get some defi gauges

I've owned about 1/2 dozen turbo cars in my lifetime, and I've never had a boost guage, so I just don't see the need for one. After all, it's all handled automatically, by the waste gate and the computer, it's not like it gives you any manual options.
Unless you mod your car, and need to keep an eye on the parameters...

yea, but thats the same as with a temp gauge, itl give u a light when its a problem, but it seems like it would be cool, as well as interesting, to know. thats just my 2 cents, and I dont even have a turbo, or know how much it costs. It can also be a little practical since you can try to keep the boost up right before you launch, but for all practical reasons its probably useless

aftermarket. some people just like to have it as a show and some eye candy to look at. I have one because i like to see how much boost im hitting and just for eye candy.
