Is this on race gas?  How did the engine stay together at 25-degrees total advance???
What kind of fuel pump are you running?

93 pump fuel, air to water intercooler with water injection before the turbo. the injectors maxed out at 6400rpm. Fuel pump is a inline 500hp one from parts plus.

I do have two 680cc sub-injectors that did come on at 3psi but I had to turn them off on the dyno and adjust my 4 SDS operated injectors.
I did not have time on the dyno to change the sub injectors to smaller one so I just ran the car until the 4 680cc injectors maxed out.
I have since replaced the 680 subs for 460cc injectors and am trying to tune this set up at the track.
Everthing I have read says 4 680cc injectors will not supprot this much hp, this is why I ask the question.
