Most of them probably have performance stalls, and depending on the stall speed, application etc are probably foot braking it up onto the stall, or just stabbing it and letting the stall flash. Never seen a 2 step on an auto, as stall converter controls the launch, not RPM limiter.
Another option could be launching off a transbrake, but that is probably rare.

I had a circle d 5c but my rpm trans lasted literally 3 passes and then I dropped a valve so I never got to find what was optimal for mine. Most guys I've seen stall it up pretty high with the footbrake.

I have close to 1000 passes doing this, with around 800 on this converter and all 1000 on this same transmission.
Results may vary though....your set-up might react differently.

I've seen videos of your car, you've got a bad bitch!
As per the below video, I footbrake it up pretty high. With my set-up, it typically rewards me with a 60 ft in the 1.27-1.30 area...versus only 1.31-1.34 if I footbrake under 3000 rpm. The car just reacts better on the initial hit if I do this.

1000 passes!
What trans and converter are you using?

I think if you're naturally aspirated, it'll probably slow you down. I'd go with a shorter tire.... big difference. Plus it's a lighter tire, which also matters.

It's a NA car for now, makes 595 uncorrected thru the auto, have 3.73s in it. Will give it a try and see how she responds

I do recommend you contact RPM transmissions for your quote based upon your application. They had one in my inbox in less than an hour after the request.
Take note, you can sell your existing set-up to significantly soften the blow of the costs.
I'll add, I only recommend this swap if you're a competitive drag racer or at least that is the primary application of the vehicle such as mine is. Was a great move for me.... not so much for everybody though.

I'm using an MSD 8733 2-step, activated off a transbrake switch that I have mounted on my brake pedal.
