ATX launch RPM
I tried searching for launch RPM and all I found was for MTX's which doesn't help me too much since I have a 3 speed auto. Only things I've done to the car are cut off muffler, High flow air filter on the TB and no carpet. I want to keep the rest of the interior but I'll lose the spare and the rest of the BS in the trunk. Any suggestions?

Your launch rpm is basically what your torque converter stall speed is going to limit it to. Yes, you could neutral drop it, but you may only get 5 feet down the track, and have a nice mess to clean up.
If you are using it for a dedicated drag car, you can get a much higher stall converter. It won't be too streetable tho, fuel mileage will suffer horribly*, and you will want a trans cooler either way.
*You will have no TC lock up either.

Hold the brakes down, and rev the engine in gear. The rpm it stays at is the stall speed. Just don't hold it there for too long, it will overheat the ATX.

OK thanks. From the testing I've been able to do to and from work if I manually shift it from 1st at 50 MPH (5700RPM roughly) to second, it only shoots down to about 4k. Should I let it shift itself at 6300 or is 5700 good since that's about the limit for the cam's powerband and it puts me back in? that range I'm 2nd
Let it shift as high as it can.
You can try little "tricks" to launch the car. Regardless of what you do, you'll probably mash the brake pedal to the floor.
One way of launching it is to "flash" the converter. You'll add just a little gas to bring the RPM's up, maybe to 1300 rpm's or so, when the lights drop and go to green, mash the gas pedal. Sometimes this little burst will let your torque converter reach a higher stall point than whatever it is advertised as.
Another way is what Bill said, mash the brake, then stand on the gas pedal, then let the brake go. You'll have to experiment (at the track of course) to see which is better for your setup.

So many neons so little time.

Personally with me currently having a ATX 4spd there is only 2 settings as far as Im concerned D(Low) for everyday driving, and 1(Low) if I want to "race" let the trans do the work for you, you will be more consistant that way
