Hi guys, do I need a remap if I'm going to change the following?

Wrx to sti tmic
Induction kit?

 

Tmic not really. To benefit properly from. a induction kit yes. But you can run filter without remap. It might throw a light up if pushed hard

 

The only way you'll ever benefit from a modification is to map it to it's capabilities.

Your ecu will only expect and ask for the flow from your current intercooler and airflow system.

You won't need to replace your airflow till you reach somewhere in the region of 400bhp. If you're desperate to change go for a K&N panel filter.

 

Have to say, best advise above. if you want the gains, remap it and IMO for the price that some companies are charging it is definitely worth doing
