Does anybody know's if it's a piggy back or fully reprogramed ecu. Our U.S. spec engine is basically the same and if they could reprogram it like the package maybe we get 300Whp 
? Is that measurement from an awd dyno?
That's probably looking at 380hp at the crank for $2400? Costly considering we only need intake and exhause piping just to product that kind of power.

I don't think it will cost that much to get to the high 300. A simple (as much as that is simple to start with) device as an S-AFC, would fix any issues that stock ECU might give us regarding the fuel delivery and the airflow limits. If you add an ITC, you will be able to correct the timing as well. Add a test pipe to the whole thing, MBC and a boost gauge, hope that stock fuel pump can deliver enough for high 300 HP and you are there. Overall, probably below $1000!
Well, turbo is the right size! Why not use the way it should be used!!

Ive heard that with stock injectors/fuel pump only 1.3-1.4 bar is allowed before fuel cuts. I dont see how 300 WHP(approx 380 crank HP) is possible on an AWD that is making only 271 at 16.24 PSI . Im guessing 350 crank HP will be closer to the number. Still not bad, thats about 80 HP for just an exhuast intake AFC and chip.
My 2 cents

380 bhp is the maximum the turbo can deliver at full boost (around 1.7 -1.8 bars). Cams would enable you to get 380 bhp at slightly lower boost.
As for where the fuel cut is, you'll have to try the car: the 7 cuts later than the 6.
An S-AFC lets you change the fuelling every 1,000 rpms, which is ok, but not as good as an ECU where you can adjust every 250-300 rpms, but it's also much less of a hassle. The problem with the S-AFC is that when you increase the fuelling, you get fuel cut earlier because that involves Karman frequency changes (which determine fuel cut). So either you increase the base fuel pressure and lower the values or you change the ECU...
