No it wouldnt be safe
So overall you got;
-Wideband gauge
That monitor A/F ratio with a probe in the exhaust.
-Boost Controller
Now you can change boost target.
-255 Fuel Pump
More fuel capacity (in pumping)

Changing boost values will greatly offset a lot of other criticals values, how will you adjust those settings? I don’t see any mods capable to do so.

Basically if you simply increase boost you’ll run lean for sure because nothing is changed in the ECU tables. Your fuel pump will do nothing about it by the way.

That here is the kind of recipe for disaster. As in every cases, you’ll proper tuning if you want to be able to run more boost, and even then maybe your not chasing the right thing because in my scenario I made a lot more power without changing the boost target. With supporting mods and pro-tune on dyno. Usually with all bolts-on, i.e; Intake, Downpipe, +++ you’ll be able to tune with about the same “stock” boost while making a lot more whp, now thats getting interesting because more boost isnt always a good thing.

More boost =/= more power.

Get that thought out of your head.

The stock injectors run out around 18.5psi in cold weather. You aren't going to get much more out of it till you swap injectors.

If you do turn it up, use an accessport/accesstuner or romraider and log log log.

I copied in the sti stage 1 timing maps and bumped boost and wgdc to hit 18 in my map. Still stock intake and exhaust, but I upgraded my tmic to the big Grimmspeed one.
