So my question is this. What all do I NEED to swap the VF39 on my forester? I have seen that a 04 sti intercooler and ecu is recommended but is it required and why? The reason I ask is because I have a vf39 sitting on my shelf just waiting to be installed.
I don't see the point in the ecu as I could just tune mine. Unless there is something else that I do not know about. I understand why someone would recommend the intercooler upgrade and yes it is the next part on my list of things to buy.
