Wow...that is some serious...impatience!<P>I am not ware of any chips available for a normally aspirated engine. Switch your air filter to a high flow one, get a custom exhaust, muffler, race catalytic converter, perhaps peformance cams (if you 've got the $$$) and <B><I>PERHAPS</I></B> you can gain 10 to 15HP.<P>You should have really bought the 2.4T; then you would be talking about some serious upgrades!<P>Yannis<BR><P>
