that gauge? its a boost controller and a boost gauge. it also has a warning thig for over boosting. There some other stuff you can do with it too, but I forget. I looked into that thing a while back. Looked pretty cool. If I'm ever in need for a a electronic boost controller i'd get that.
lol i hope you have money because i think it costed a little bit more then my turbo. I'd definately get one if you got the money. In the future I'm want to get defi gauges, but thats going to cost me a a nut and a half to get the whole gauge setup I want. What kind of gauges are you going to get?
