Default Subaru WRX 02, question about turboxs boost controller

Hey everyone! Bought my first car yesterday (02 WRX) after searching for several months and lurking on the forums to learn more about the car. Everything on the car works perfect, but I noticed a little toggle switch covered by a red safety cover that leads to these under the hood...

After doing some more research, it looks like you can control your boost levels in two stages, but I am unsure as of now on how you adjust the boost levels or what they are set to now. Since this was done by the previous owner and not me (one owner car before me) I'm not sure if he set it up for a moderate boost or something more. However, this is the only mod that basically came on the car other than a sway bar, and the guy kept all maintenance records and took meticulous care of the car which leads me to believe he didn't set it up to run crazy high boost. I have it flicked down now to the down (which I'm guessing is off) position, and my two main questions are:
Can I basically keep the switch set to off and the car will be safe?
And can these turboxs boost level switches even go up to crazy amounts of boost? Or am I safe either way? Thanks.

where are you located?

the problem with manual boot controllers like that, is fuel scaling doesn't match the increased boost levels.

they need to be tuned for to be operating correctly. I'd contact your local tuner, and see what they recommend.

You should take your car over to GST in Hayward, and if they can't help you out, there's EQ Tuning in Fairfield

So I guess I'm not understanding all the way. These things need tuning every once in a while to recalibrate them? Wouldn't the other owner have already tuned them when he purchased it? I'm basically unsure of what tuning does and if going to a shop would be the only way to find out about these things

My hope would be if the car is tuned for the higher boost setting all the time. That way, if you're running on the lower boost setting, you'll still be safe. You should really install a boost gauge and see what the difference is in boost between on and off. I would hope the previous owner had the car tuned and not just slapped it on. Getr ahold of your local tuner and he can confirm with a quick scan of your ecu.

Those access ports look pretty expensive. I guess I'll just try to read the boost readings with my boost gauge. What is the safe psi amount that a stock 02 WRX should be running at? Isn't it around 12 psi?
