personally I like JPC in thomastown.
Although I'm not sure if they have an AWD dyno, so you may want to contact them first if your awd (I have heard of them using creatd's dyno though)
Cool,depends how far youre wanting to go with it,/ tune it.
You might need a 2bar map sensor upgrade etc..
My guy loui installs and tunes them and motecs for a living,if youre from the west (live close by)
il give you his address an you can drop by an have a talk with him
if you like. Up to you.
I'm pretty sure CREATD in Campbellfield do Microtech too. I found Rob to be a pretty upfront kind of guy and he did a good job tuning my car when I took it to him.
