the answers to specifics are more attainable from the current knowledge of fellow A4 drivers and Forum readers. My '99.5 1.8TQTip will never see the inside of a racetrack(If I had found this site before I purchased I would have at least opted for the sports suspension.) Despite my modest expectations for this car, I would like more power with regards to all driving situations. I will be rolling thru 5000 miles on the way to relocating in Arizona soon and am planning to have my servicing done at Scottsdale Audi. I understand they will also install a chip w/out any warranty hassles. I have yet to decide on what chip best suits my performance desires and this A4, and what other options I may need along with chipping. I also plan on switching to a synthetic oil for the AZ climate. I would like any suggestions that would help me come to reasonable conclusions and make what I consider a great vehicle even greater. Thanks.
