It's got to push ALOT of air to achieve that, for it's size.
You just repeated what I just said about the ceiling of the turbo.

Why 300whp should not be a problem? You see a dyno above showing 283whp with only software. So another 15-20whp from a full exhaust, intercooler and stage 2 tune should be beyond attainable. I saw 7whp just from a catback on a load bearing dyno. That would have you at 290whp right there.
