I just timed my S4 from 0-100 Km/h (62,14 mph) less than 2 weeks ago, and got 
numbers between 5,9 and 6,3 seconds. And a couple of complete misses at 7.0 
and more :-(
We were 2 persons switching between driving and timing, with a quite 
professional stop-watch. But then again, 1/10 of a second isn't much, and it 
was manual timing. There's allways the possibility for errors, both in timing 
and in speedometer reading. 

So, what's done to my car? See the "Re:95+ S6 performance upgrades" section 
below.

Mine is an ABT chip/ECU mod., the turbo pressure is 2.2 Bar from 3000 rpm on 
third. I have seen the 2.3 number some times. The ABT mod. should give about 
40 additional "beer-horses", to a total of 270.

Nice! Can I do this on my '93 S4?

I have an ABT exhaust system, which should give a 5% HP increase. 25HP sounds 
like a lot. So mine should total up to about 283HP. Give or take a few ponys.
I don't know the price on this, since it was on the car when I got it.

I have this too, I think they are from ABT (a mechanic told me so). Mine is 
lowered by about 1,2 inch (3 cm). Not only lowered, but also fitted with a 
more sporty suspension than stock. Which means a less comfortable one. It 
makes a difference in handling, no doubt. But I suspect it is the suspension 
that does most of the work, the lowering is more for the looks. And it 
does look very cool with 17 inch wheels and 245/40 tires. :-)
I Really look forward to get them back on as soon as the snow and ice 
disappears.
