Hi guys - apologies for this question as I can imagine it has been done to DEATH but I am new to this forum so just need a little guidance.
I am jumping from an BMW M3 to S3 (2002 or so); & from what I can gather, I NEED to chip the S3
Also from what I have found so far, the best way to go is either a Revo or AMD chip (or possibly Jabba??)
Just want to see if there are any noticeable differences between them?
Was also planning on putting a new air fitler on it....K&N all the way??
Also I am also looking at an unmolested S3 tomorrow - anything I should look out for in particular?
Thanks in advance for your help guys!!
