If you are really only running 5* of timing then you may be shocked at what the hp difference would be. Do you have an EGT setup? I would be a little scared to know what the EGTs are at with so much boost and so little timing.

another thing is we could not get the turbo to build boost past 40 psi no matter what.i tried a manuel boost controler and i even unplugged the vacum line to the wastegate to see how high it would go.it will not go past 40psi.so i think either i have a boost leak or maybe the turbo cant build past 40 psi which i doubt.

You should be able to run SOMEWHERE in the neighborhood of 15-19* up top. If you are really only running 5* of timing then you may be shocked at what the hp difference would be.

I run Torco 118NOS and have found that the cars generally like higher timing numbers with it to make the power. You should be able to run SOMEWHERE in the neighborhood of 15-19* up top.

Whatever the .85 A/R TS hotside delivered, the 1.06 should do better, so that shouldn't be an issue.
The stock head is likely somewhat of a limiting factor, but I can't say to what extent. Logic implies that the greater the power potential, the more significant a limiting factor it would be.
I agree that the turbo isn't the problem. There is something else amiss. A pressure test is always a good first order of business.
What WG spring set are you using?
I agree that with only 5* of ignition advance, there is either power left on the table, or, if preignition was encountered near that point, there is something amiss that is aggravating the knock threshold. Again, make a pressure test to verify that you don't have a leak.

Saw this video testing a FP GT4094 produced 760whp 536tq. Its really hard to see the dyno graph, but it is posted.
Anyone know how much boost this evo was running?

I just dynoed 629/490 on the GT4088R (.95 A/R) on E85 Pump Gas at 25 PSI last weekend.
It will do 700-725whp on C16, however I am not trying to max out this setup.
I have decided to go to a GT42 or GT45R, as I plan to drag race the car next year.
I paid $1800 for it back in June, and will take $1400 for it as it sits. It has approximately 500 miles on it, and is in perfect shape.
