The Best of Mercedes & AMG
I have to admit, I'm really surprised you can run that much boost on this motor.
I know that a completely stock L99 motor with a 2.8L twin screw (it's a GM powerplant... basically the same thing as the LS3...) run at 16 psi bent all the rods during a track outing. But, the engine held up for numerous runs at like 12-14 psi.
That motor was 10:4 CR.
Obviously, I would wager that the M156 is more durable, but it's also higher compression.
I really hope your engine stays safe. And I'm sure with all of the engineering and R&D that has gone into your car, almost everything is accounted for. I did notice that your AFR looks very conservative, which is great. Obviously, that point where the line goes a bit rich must have to do with the slippage on the rollers.
I wish I could see your car run. But, I will be unable to attend. I wish you the best of luck.

If you want the dyno sheets or details about this build, you may have to google this phrase exactly as is:

Congrats again Jim, the car looks like it is making a LOT of power
Either way a 63 with a SUPERCHARGER

Good luck!
and if not then these 63 motors are not what we all thought they were
A 250 shot of nitrous should be ok then
I've hit the 612rwhp a few times but stopped the runs , wasn't sure how high the #'s would go before something bad happened..

I am 100% they lowered the compression ratio to run forced induction on the car.
