[mestew87]

Hi i am a newbie here. I am soon going to be looking to upgrade to the S4. I am looking aroudn for tuning companies etc but most are located in the states. Can you tell me if there is any difference betwen the euro spec and us spec. Also what would you say is teh weakest area of the s4

There are quite a few UK tuners for the S4 in the UK, this site for one is run by one so do a search and your see quite a few threads regarding it.

US chips are no good for UK cars but other than that most parts are interchangeable.

What you should be looking for is upgrading to RS4 spec or higher as this is wear most S4's set there goal for so things like RS4 intercoolers Y-pipe, K04 turbo's fuel pumps and so on.
