So much for 400 whp max...

That's a massive gain from just a tune. And to top that off, Carlsson is an authorized MB Tuner, so Mercedes will still honor the car's warranty with their parts on it.

Show me the actual gains on an independent loading dyno. I guarantee you it won't surpass 400whp

This man knows what hes talking about!
Another thing is that this is the same turbo now used in the newer Single tubo BMW 335i N55 motor.

LOL. Maybe on stock turbo this will be true. Depends if the aftermarket takes off. Direct bolt on turbo kits I do not consider major upgrades. The block is sandcasted w/ a closed deck, and the whole bottom end is forged.
Let's look at another FI 4 cylinder car with strong internals.
A stock srt-4 dyno's around 230whp, 300whp can be extracted with bolt ons and tune. Granted a stock srt-4 doesn't push 26.1psi stock, circa 14-15 peak.
Turbo swapped srt-4 50 trims make 400+whp, This can be done relatively cheap, even the 50trim can run on stock internals.
While GT35 turbo srt-4's have broken the 500+whp mark. Others are even higher. Red Sled comes to mind.
Do not discount a car just because it is a 4 cylinder. This isn't 1970. That turbo 4 stock is dynoing similar to what my modified M113 V8 can muster.

I can't wait to hear what the aftermarket can bring to the table for this car. According to the information I have looked at from European reviews, it seems to be well sorted out right off the showroom floor.

Guess we'll see what GMP Performance has to say about that, if anything. They're already selling the modules for the 250 at least.
