Don't think it matters much but just realised you mentioned the problems
with the EJ257, the JDM STi's have 207's.
I know there has been issues with the 06/07 ADM 2.5's when they have
had
TBE exhausts put on without a tune as they are more sensitive than
older models.
But it is tuned for 100 RON so babying the car until tune is just extra
safety and wont hurt me to drive granny spec for a few days.
