What's the most horsepower made on a stock turbo?

[Turbo3Iroc]

I made 275 HP on a stock turbo and stock cal with overboost removed. That was with the all of it setting and the spike up to ~22 lbs and drop off to redline. Can not recall what the car ran at the time but it wasn't useful power with such a peaky powerband.
