I am not sure about boost gauge being standard on the STi, but I am pretty sure you can get it as a factory option.

I wouldn't worry about voiding your warranty with a boost gauge. Most delaerships should understand the importance of a boost gauge. It's only a T off a vaccuum line, i.e. the fuel pressure regulator line.
