Just like the title says, anyone running a 2-step w/o a brake? Do you have it wired to the brake lights or ????

Any other suggestions for the 2 step other than the LPE piece? I don't even know if there's anything else available, it's the only one I know of that can be ordered.

yep you can do that,
just use a switch 12 volt source without the tran solioinde ( spelling) hooked up..
it will act like a 3 step..

Anybody having luck doing this? I'm worried the brakes won't hold if the car actually makes boost at the line and I'll be wishing I had just put a t-brake in while the trans was out.

this will almost certainly be the case.

Thought I would update this in case anyone stumbles across it.
I went with the LPE 2 step with the brake lights wired in series with a toggle switch for activation.
First test - it builds 4 psi almost instantly and slowly climbs to 5 after a couple seconds, I might be able to get another pound but I don't plan on waiting 15 seconds for another psi. This is at 3000 rpms. No timing retard, no adjustments in the tune, a/f is about 11.5, methanol just barely starting to spray.
It annihilates the tires on the street, I hope it'll stick on the track!
This is on a 346, APS twins, 3600 PI converter in a 4L80.

So the brakes hold it at 4-5psi?

What stall do you have?

hope it works on my 3k stall. I wonder how fast it would build boost if you tinkered with it.

I am trying to get at least a couple psi with my rear mount doing it this way.
