What turbo? Has it reached choke point? What's your exhaust map/iintake map ratio like?

No idea, that's a massive turbo for that kind of power. I thought you'd be able to maintain 300ftlb for higher into the rev range with that sized turbo. It's only just starting to work at 450hp.

Perhaps there's something to be gained in the tune.
Are you knock limited?
What's your ignition timing values?
Are you using decent quality fuel?
What's your exhaust system?

What did your tuner say the was the limitation?
Supposedly it had a boost leak but so far I have not found it, check everything and nothing I do not understand is because the boost reaches those revolutions if you see the graph at 7000k it is that that graph goes up there the pounds of boost arrive I do not know if it is that the size of the turbo is very large or I also think of the pistons that are 10: 1 I don't really expect at least 550 @ 600 I don't know if I'm asking a lot for the Oct of gasoline but there are a lot of factory engines in those numbers
