Aren't they.
Key things there though:
1. The engine is revving to 7000 rpm and the peak is at 6800rpm. I'm assuming this is a function the UTEC gives you to override the stock rev limit. At 6000 rpm power is at 425 bhp-ish, which is more realistic (but still great!)
2. I believe a 2.8x pulley is being used. In this instance, you'd expect to see boost around these levels.
Still - good to see great figures.
