The 3+ works great in my setup at 760rwhp, but I haven't launched it on slicks, yet.
I'm not sure what your setup is (turbo/nitrous), and I don't have quite that much power, but I used to launch hard with the bottle on, and it worked great with the standard 3 on a 10" slick. I stepped up to the solid hub 4+ to make it launch even harder. Surprisingly streetable too. I only launched it a few times with slicks on the street to test it with the 4+, but never at the track.It seemed more aggessive than the 3. I won't be sure untilbI get it on the track though.
