The only way to launch a boosted tour, or pretty much every low displacement or 4wd car is to ride the clutch. Practice revving to 3k or 4k rpm, start with the clutch right at the friction point, and slowly feed in throttle as you BRISKLY (not too fast) release the clutch. It's really like a more dramatic version of your first time driving a stick. Releaseing the clutch too quickly hurts us in two ways, it shocks the drivetrain which could cause wheel hop or a sudden nearly complete loss of traction, and it bogs the engine.
Practice this an you will be amazed what it does for you. Off the launch I can stay a car behind cars the launch very well (eclipse gsx, evo, mustang gt), and this was pre-lsd.
P.S. If you launch below the rpms that your spools at, practice launching then going to half throttle right as you hit that point. It takes quite a bit of practice to do this, but the last thing you want to do is overwhelm your tires. The rool of thumb is tires grip to a certain point, but after you pass that point, they give up.
