Question Need Help Breaking up when boost comes in........

OK guys here is what I have done to the car. I have a T4 T04ZB turbo log style manifold. For fuel I am running a Supra TT fuel pump 700 secondary injectors and a safc2 to tune with.

Now the problem is no matter if I am on low boost wich is 10lbs. or if I am on high boost wich is 17lbs. When ever I step in to it really hard it falls on itss face and breaks up then it will clear out and take off like a rocket. I have tried everything I know to do and can not figure it out. Can someone please help. I need to get this fixed like asap I have a big race in two weeks and need to get it fixed.

Thanks in advance guys.

First of all, WHAT "T04B" are you running???
"T04B" descibes a *famliy* of Garrett turbos, which are capable from 200hp to over 400hp!
If it's on the bigger side, your 700's in the secondaries are NOT ENOUGH FUEL - even with the Supra fuel pump.
You're probably seriously leaning the motor (at 17psi?!?!?!), and you're lucky to not have blown it up by now.

Second of all, the Turbonetics 38mm WG is 1) a piece of CRAP, and 2) it's too small for your set-up.
Be prepared for some major boost creep!

The to4b I am using is the 60 a/r intake and 96 a/r exhuast. The said it is good to 400 rwhp. So what you are trying to say is i need bugger injectors...........

Might be an abouse(sp?) one but have you checked your spark plugs and sparkplug cable for proper resistance?

And I agree with RETed, 700 Secondarys is no where near enough for 17psi.

Throw those on your primary rail and get some 1200 or 1600cc and a standalone.. you need to be able to tune ignition for that high of boost.
