Sluggish audi?

[philj]

Picked up a urs4 the other day and it seems to be a bit sluggish, I can only compare it to a friends which I remember being pretty fruity. I've given it new plugs, oil, and filters this week which gave a mild improvement. Was wondering if there was anything that can be setup, a few standard tests?

The boost gauge on the computer seems to stay at 0.3 off throttle, goes up to 1.3/1.4 when you open it up.

MPGs 12 around town...

Any help would be much appreciated.

Digital boost gauge shoud read 2.2 on overboost or at least 2, I would think you have a boost leak, so do a test, you can find out how to on hear just do a search.
Also try unpluging the M.F.T.S and see if it makes more boost. MAF is a likely candidate as well.
The list go's on so you have to eliminate things one by one.

I had my S6 feel the same, and returning c--p MPG, it turned out to be the dump valve. Easiest thing to do is take it off, suck on the small pipe and put your tongue over the end off it, it should hold preasure. It cured my car, hope it does yours
