Can you elaborate on what you did to improve milelage? I suspect my Tip will never be able to do as well as a manual. I have K04's with aftermarket downpipes, high flow cats and an adjustable fuel pressure regulator, making fuel pressure adjustments only seems to change the accuracy of the milelage counter..

I worked on a custom tune with VAST, also tweaked part throttle fuel trims using Lemmiwinks. My fuel trims on block 032 vagcom engine are very near 0%. There are also other things you can try, I found that sometimes driving at a slightly higher RPM,different motor efficiency actually achieved better fuel mileage.

If I do mostly city driving, I can average around 14-15l/100km. That means my tank of 70liters allows me to do 350km max ONLY in city driving which is not bad LOL given the fact that my foot is heavy. hehehe.

Now I work far from home and I mostly do highway driving, I average lately 600-650km per fuel tank and trust me when I say MY FOOT IS STILL HEAVY. I get that mileage flying down 140km/h and over 70% of my trip down to work.

and let me add that I removed my catalytic converter because they were clogged with crap and it was causing my temp sensors to fail. So I thought not only would I gain 1-2psi on my turbos but my fuel consumption would rise BUT i didnt see a crazy increase of fuel consumption but I did feel the car is pushing a bit more. Hope this helps.

You should be getting 12 to 13 liters per hundred km in the city.
Things to check are:

Tires - what do you have? In general if you have fancy like "Sumitimoto AHASUKA NIPPO**** RXS DX RPM ZOOM" and they claim to be so good it is nothing good. Just get Michelin.

Tire Pressure - it is not 32 psi as per average Canadian Mechanic - the car is not a Ford. It should be 40 psi minimum.

Spark Plugs - Forget Champion and similar V GROVES, check either the plug is made in Japan and do not buy it. Your plug needs kick - use 4 Bosh Platinum or Iridium. They generate 4 sparks at once so fuel burns better.
Be warned about Iridium - the car runs out of control above 160 km/hr and behaves like a jet airplane.
I had fun with them in Oregon this year passing American Muscle cars as if they were parked.
(They had to slow down on the curves to 180 and I did not feel the need for it on a Quattro)
Got fists and fingers and also respect at the end of it.

Battery - Replace it every 3 years. With old battery you do not get enough AMPS to power all electronics properly.

Gas - switch gas stations and find the one that your car likes.

Air Filter - How old is it - AUDI NEEDS lots of air I use K&M or something like that

Gas Additives - Add fuel injector cleaner every 2 months

Hand Brake - it can be stuck. Check either the brakes are hot.

Carbon in the engine - add Seafom to gas or Techron from Chevron - it works!

Air Throttle - Use DEEP CREEP to clean it, or just spray your air filter with it and drive.

Tiptronic - when I use Tiptronic the milege is better but I do not know why?

I personally use NGK BKR7E, great copper plug, gives consistent spark, even under high boost

Did you use any other type before or is it all you know? I am just trying to get the feeling for it as I used them on my Jetta 20 years ago and I remember being happy about them. They lasted 20,000 km as I remember.

I used the OE replacement bosch, also RS2 recommended bosch. I like the NGK for price point and performance

I pay hidious bucks for Bosh.
