EE9 - Checked with a friend who I consider pretty hands-on with mods from Singapore who often brings his DC5 to Sepang. His pevious car was a STi. Accordingly to him, your boost level is in line with the mods you made to ure car plus, he does not feel that it warrants any ECU tuning. As long as you monitor the oil temp, pressure and water temp., you are OK. So, there u go, you can feel a little better the next time you launch down an empty road. Having said, it is still wortwhile getting your local mech's opinion for that little bit more comfort.
dunno where they get their 'kopi-o' license... lolz Orang Kampung punya driving lar...
