Did some shopping for a few extra bits today.
Got a K&N Panel Filter... I can definitely see how much better that flows than the stock unit just by looking at it.

Also got a new fuel filter...didn't realise that the 06/07 STi fuel filter was in tank as part of the pump assembly serving as both a pressure reg as well as filter.

Tomorrow it finally gets tuned, its been a very long wait.
