Wouldn't be the first time cars from the VAG group have had their power advertised conservatively though.
Take the Golf E30 & Leon Cupra which both used a "detuned" version of the S3 engine. Plenty of independant dyno's showed these cars were making almost as much as the S3 as standard and S3's were making well over their stated figures as well.

Sounds like I'll have to pop up to Vixpy @ Surrey Rolling Road and get this checked out then 
As for fuel consumption, I checked the onboard computer just 2 nights ago, and over 2500 miles of mixed motoring the average is 20.7mpg.
Resetting computer 1 for a light footed motorway only journey it will briefly hit the 29/30mpg, but thats if Im on the M25 and a speed average of 65mph.
But who cares?
ETA: I had my previous A4 DTM dynoed and it was bang on manufacturers claim

Righty ho peeps. Popped over to PH's very own rolling road officianado, Vixpy1 at www.surreyrollingroad.co.uk this afternoon (he's an all round good egg, despite the rumours 
)
I'll post the graphs up when Im at work tomorrow, but basically, if my result is correct/average for the B8 S4, both the tuner quoted and Audi are telling us porkies. The tuner for over stating and Audi for understating
Peak HP was 347, peak torque 330 and rear wheel HP (I believe this is rather a black art guestimate) is 272
The Scooby boys who were there when I arrived and stayed to laugh at the boring German car looked a little green round the gills as I drove off

I think Audi are being a bit conservative with quoted figures these days, after all the hoo har with all the B7 RS4's being 20+ bhp down.
I found out this week, B8 S4's improve masivly with milage (as in running in) I drive our demo when it had about 20miles on it, and it was very disapointing (compaired with the V8 S4). Drove it again when it came in for first service 15,000 on the clock, its a different car, feel like its gained about 50bhp.

Nice one Fubar, would be really interesting to see the graph.
Which gearbox did you go for and how many miles have you done now?
TT I noticed the same thing with RS4s, brand new they didn't feel all that exciting. It's a similar story with cars that get mollycoddled, they never feel as fast as cars that get used properly.

Vroom vroom 
Lots of talk about extracting more power from these but doesn't seem to have hit the UK yet:

MTM already offer a 430bhp/515nm upgrade (and if my previous experience of MTM via Kim Collins is anything to go by, these figures are conservative ). Plus a Miltek

But do I really need two 430bhp cars in the garage?
