Or you could try vents? They are more subtle.
On the contrary I think tuning it makes it more reliable, it’s possible to run a safe tune and lower the boost. Can even retain stock power. May need specialised ECU and specialist for that sort of 3D tuning tho.
Hopefully not too many issues there and ECU like what you did to the car. I have a few friends with untuned modified car, runs so rich it stinks lol.
