Plus one to vipec if you want e85 can get it setup and tuned for flex at allstar I've recently had mine done best mod ever

using the Perth-WRX mobile app

Thanks guys

I will keep a look out for some injectors as well

Thanks for the ECU info. Mine is daily driven, work and back and on weekends, everywhere! Don't need to many extra features, probably go with the cheaper option and also depending on what the local tuners are using. I am in Melbourne, Victoria

ECUTEK seems to be common, with the 2 tuners that I use for my other cars. There is a place that does Vipec but that's on the other side of Melbourne.

Vipec also seems to be out of my budget!
