Hi, I have an Audi A3 (52 plate) 1.9 tdi sport (130bhp). I want to increase the power slightly. I have been looking ar revo and they can map it to 170 bhp. I am thinking about this, however i would be happy with 140 or 150 bhp and dont want to spend the 400 quid on revo doing it to 170 bhp. Is there anything else i can do to give me 10 or 20 more bhp?? i.e a K&N panel filter, or an induction kit, or a small chip. There is also this kit on ebay?? Anyone tried it before? Its cheap but i am not sure its trustworthy. http://cgi.ebay.co.uk/20-BHP-AUDI-80-100-A3-A4-A6-A8-S2-S3-S4-QUATTRO_W0QQitemZ120170896213QQihZ002QQcategoryZ10372QQssPageNameZWDVWQQrdZ1QQcmdZViewItem http://cgi.ebay.co.uk/PERFORMANCE-CHIP-BHP-AUDI-80-100-A2-A3-A4-A6-A8-QUATRO_W0QQitemZ280163476918QQihZ018QQcategoryZ32094QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Thanks.
