12-13% is what regular M6 SS have for drive train loss since they dyno about high 360s low 370s. I think 580 hp is pretty accurate.
The autos are usually about 40 rwhp lower, so I'm guesstimating they an auto ZL1 would dyno about 460 ish.

But isn't that using the factor from a L99 auto comparison vs a LS3 m6 instead of an auto CTS-V vs m6 CTS-V or did I misunderstand.

There won't be 40 rwhp difference on the ZL1 (More like 20)

The LSA flywheel hp is the same 580 for Auto or Manual where as the L99 is 26hp less than the LS3 right off the bat.

Oops, yeah, I forgot the auro guys get jipped 26 HP. Yeah, 20 rwhp is better.

Puffs out the right tailpipe at 2:36 and 3:32 any cause for concern? Nothing out of the left that I can see.

500+ rwhp, and 520 rwtq, from the factory on a mustang dyno. Nothing wrong with those numbers at all. Now lets see what Lingenfelter does with them from here.

Yeah I saw that too, hmmm, I am not a mechanic but I would be concerned if it was mine. Maybe there is something to the suggested break in period.

That it puffed from one side of the engine and not the other is what got my attention.

That would be called detonation, on that run. Nothing to do with a break in period, just us exploring the performance of the vehicles at different temperatures and heat soak periods to see the effects of intercooler system efficiencies when heat soaked etc. we are just establishing where the limitations may be before we explore extreme power levels. its all about understanding what the production set up is capable of before pushing it to where we wish to be with these cars. First notes are the intercooler efficiency differences between this set up and the CTSV, inlet depression, obviously exhaust system backpressure, etc.

Do you guys plan on getting some 1/4 mile runs before the modding starts?

I'm at work, so i can't view the video to see if you ran through the gears "hard" or not. But if so:
Did you notice much difference between throttle input and actual % throttle body opening between shifts to get an idea of how much torque management is dialed in?

It is the same hard parts as the CTS V, so I think we know what one will do.
