If Scott tuned you, you should be money.
You need to invest in a wideband if you don't have one. Should be a day1 mod like the 255fp.
It's all in the tune man.
Edit: There is no magic PSI number. That number could be 10psi with a Dom3 and a shotty tune. I mean it's an STi your ringlands are due to give anyhow.
j/k
