Audi s3 2008-2009 What can I add to my white audi s3 and improve the look of it from behind , also what would be the best choice of tuning and increase the performance
Performance you can do two very easy things. 1). Re chip ECU for a increase of about 10 HP to 20 HP. 2). Install free flow headers and exhaust for 10 HP increase. Both are legal and can be done a competent mechanics shop. All of above done in a day and for under a K which would be 3 or 4 K under a blueprinted motor.
