i checked those pictures and i couldn't tell. The factory boost gauges read in bar(which is very gay). They do read higher than 17psi but again, it's in bar. I've also read before that the stock Subaru gauges aren't very reliable. Especially when dealing with an upgraded or aftermarket turbo-charger.
