Welcome to our world.

I wouldn`t fit a Superchips, i think the general feeling towards these on the Impreza is poor. Try Link or Unichip. Do a search on these subjects and you will be reading all night, even though i have asked these questions in a thread myself tonight.

Never heard of ARC filters, so cannot comment.

Have fun with your motor http://bbs.scoobynet.co.uk/biggrin.gif
