MTM turns up the wick on the 2010 Audi S4

That is a lot of gain by just an ECU tune... @ 30% increase!

I happen to agree with you here Ben, it does sound excessive. Unless the true figures for that engine are closer to 360hp which given it's acceleration times and weight would sound more realistic than 330hp, then it's only a 20% increase that though still high is much more believeable.

That may be the case. 20% is very doable with a mighty fine tune. I believe that is the ballpark for the old B5 S4 chips.

I was frankly astonished they could get 30% more power from ECU alone but when you look a bit deeper you see that it's only about a 15% peak torque increase. The stock engine has torque managed to drop off at about 5.5k revs, the MTM upgrade ups peak torque sure but also let's the peak torque stay much further up the rev range. Audi haven't opened the taps fully on this engine!

Very nice numbers from the MTM S4! However, regarding character, I think its a deliberate choice. Indeed, those who tune Audis typically seem to be more into engine and exhaust modifications than suspension tuning as far as I can tell - I think a full fledged MTM S4 with revised suspension and brakes and the sport diff would be much closer in spirit and performance to a RS car than only a partly modified one. Of course, you could in turn tune a RS car to be more hardcore also - but the character seems to be more by typical customer choice than intrinsic to opportunities.

Slightly off topic, MTM or other tuning and those of you who have bought it: do you worry about durability and resale value? I am asking because I once had a MTM re-mapped S3 and while I really loved it, it was sadly not exactly an advantage when I finally sold it.

I've never had a durability problem with MTM - they are pretty thoughtful about how they tune without overdoing it. They also have a strong links with Audi. Then again I've never gone beyond a stage 1 software tune. New intake, exhaust, fuel, turbo, nitrous etc is a whole different game.

With regard resale, the new MTM cantronic tune uses a dongle that plugs in over the ECU. You can simply take it off and the car reverts to normal behaviour. If you happen to buy another Audi then MTM can just reprogram the dongle and you can plug it into the next one.
