Another Southern local!
We're up in Dunedin, with a 2011 STI, We had it on the dyno when we first got it, and I think it was 190wKW..
We've since thrown on an Nvidia R400, and are awaiting delivery of a PBMS Cat-less down pipe.
Hoping for 225wKW, with the down pipe, exhaust, a new fuel pump (DW65c will be installed), and probably just a high-flow filter.
Tuner wise we haven't decided yet, either APET, or maybe Rapid In Timaru, haven't decided yet!
I've had my rally car tuned a few times at APET, with no issues so far.
