Yes, and control too. Launch control will keep the RPMs the same, while your foot is on the floor. If you watch my launch on my videos, you'll see the engine stays at 4,000 when I launch, that's launch control keeping it there. Which keeps the boost/power/torque constant for each launch vs different on every launch without it.

Without launch control I run 1.9-2.1 60' times depending on how hard I slip the clutch to launch. If I don't blow the tires off.

I've got a brain built diypnp that has 4 output wires; power, ground, o2, and ebc. I've read into adding launch control a few times but as soon as I take the case off the MS I start crying and frantically try to put it back together.

Depending on what type of MS it is, and if you don't mind downtime, Brain could probably build in launch control for you.
