Hi guys - so being a bit of a noob on this but I think I have made the decision to go with Stg 1 Revo. Based on its wide user base, perceived quality/reliability and the fact its 20% off at the moment. That aside, if I were looking at any other mods, induction kit or exhaust that could affect engine performance, is it best having these installed before or after the Stg 1? Im thinking about Revo programming here, or does the ECU become accustomed to these items when installed after a few 100 miles? Also - can somebody tell me exactly what is required for the full potential of Stage 1? I have a 2010 S3 S-Tronic. I have searched with no luck! Thanks.
