Sorry to disappoint but you may have only 300 hp. The engine block family may be rated for up to 330 hp, but yours, as tuned, may be 300. I had a similar situation with my Cummins ISL engine, which proudly wore an engine data plate stating it was an ISL 400 with 1200 lb-ft of torque, but the version installed in my coach was actually derated to 370 hp. They did that by limiting the turbo-boost and flattening the torque/Hp curve slightly. The following year the same engine became 400 & 425 hp instead, again by re-tuning the electronics & turbo. All magic!
That enables the engine manufacturer to offer multiple engine models without actually building different engines. That may be simply for marketing reasons (vehicles with bigger engines are usually higher price or upscale marketed) or to meet some regulatory or mechanical restriction on engine size.
It's also possible that FCCC simply ran out of the 300 hp tuned engines at the moment your chassis was built and substituted the 330 hp version, which is identical except for the tuning.
