Any thoughts on which vac line I should use??
I'm going to dump a can in the gas tank also. Hopefully it will improve my abysmal gas mileage and make sure I'm ready for my chip (couple weeks).
Also anyone thinking about getting headers, think we could band together and get a few folks in for a group buy? And anyone know how hard the header install is?

I record my mileage religiously and there was only a slight increase for that one tank. Not to say it isn't good for your car. My mechanic swears by his professional cleaning machine. If you want it done right thats probly the way to go. What mileage are you getting? I get 21-22 in the summer (usually no AC) and 18-19 in the winter.

My A/C is on from April thru Halloween and I only get about 17-18 MPG then, and only slightly better (18-19 MPG) in the winter with no A/C.
Why is your mileage so low in the winter?

I always drive with the sunroof open. Usually that keeps it cool.

I learned about seafoam only recently and had in the meantime my engine de-carbonized, which I think is the process jgurhrie was talking about (done by professionals). Cost me about 100 buck. Not sure yet what it did with the mileage, since I did not watch my mileage in the past. I just pour there the highest octane and the best gasoline- may not be the most economical way, but the car drives the best. BUT after the decarbonization I have noticed the car pulls better and shifting is much smoother. Almost looks like the car stays longer in the gear and the pull in that gear is constant- meaning when it shift to higher gear the the RPMs will of course drop but the transition is more smooth. The engine definitely liked the decarbonization. The Independent audi shop also told me that a lot of sh*t was coming out of the car when they did it.
GAS MILEAGE- I started to watch it again- because it seemed to me it's quite low. But I think what happened is, they adjusted my tire presure in service too low- reccom. for A6 32 rear and 36 front- I keep it around 40 psi front, rear and it makes HUGE diferrence in gas mileage.
