300 whp looks like about 25% efficient with 4X550s (this is a little high for a stock turbo configuration) I would be worried with 4x550s at 300whp on boost.

Still, we're talking similar efficiency numbers, or at least it sounds similar to my ear.
The person I know had to shut the car off on the dyno since the NA injectors' duty cycles were getting to high at 197 whp.
