The injectors aren't the issue... The DI pump can't handle much more. I have a KB Boost-a-pump and was running a 3 bar sensor that let boost go into high teens. FRP starts to drop off rather quickly. No one is certain just how low it can go before the engine blows, but when it starts affecting the A/F... you will be toast.
Also getting all that power you are wanting, to the wheels is going to be a mean feat.
Rear can only handle a max of 150 lbs torque before slipping. So, you better be running DR's on the front, or the torque going forward will cause the fronts to spin, with rears hooked up and clutches slipping, which will either cause the AWD system to shut down or if you can somehow over-ride the computer, will grenade it.
The night I turned the 12.9 in my Flex, I had system shut down on 9 of 12 runs.
My later 2 12 second runs at Bradenton, were when temps were in the 70's and I was running DR's.
Who is tuning your SHO?
Good Luck!
