Not unless I want to drop more money in it. My injector duty cycle is 86%. That's pretty much maxed for stock injectors for me. Going into the 90's is just too risky.

If you ever want more reliable power, pick up an Aquamist water injection kit, and you'll be able to run 15 psi with 11.5 AFRs all day long, and arguably a 'safer' setup than you have now from an anti-detonation standpoint. Of course, the longevity of the stock twins will probably be compromised a bit at those levels.

Off topic but it clearly says chassis dyno. All DynaPacks are chassis dynos. I did see the flywheel correction you mentioned and it is purely a calculated number based on his 368 wheel hp and a guess on drivetrain losses. Still, great numbers but far from 433whp.

Basic question, and sorry if I don't understand what was done.
With all the cross over welded up in the manifold, and the prespool gate removed, how do you control the boost from the second turbo? The waste gate only controlling the primary. How is the inlet pressure controlled in the secondary turbo?

The wastegate is only bleed from the primary turbo. The crossover to the pre-spool opening is eliminated to reduce the turbulence in that area. Since there is now no exhaust flow transition between both turbo's, this conversion basically utilizes the air flow of each individual exhaust runners and flows it to it's own turbo. From what I can see from the pics, there is still some room for improvement on that manifold to decrease lag. Anyone who understands Bernoulli's principle will know exactly what I'm talking about.

Tthe prespool area is blocked to the turbo port ,the crosstube between the two turbos that goes to the wastegate is in the main manifold before the turbos . BOTH turbos are vented by the wastgate . I am not so dumb as to not control both turbos .
