Well that's whats so awesome about this trucks is the 4x4 boosted launch.....I would try a half boosted 4x4 launch and get keep going up till it gets to the point where all your doing is lighting up the tires then back off the boost.....you should be ok, just don't get carried away with it....baby steps

When I am racing on the street I reach down and throw her out of 4x4 after the launch. But that is just me.

Shut it off but it won't dis-engage till you let off....so be sure to let off all the way before you make the turn around.....it probably won't hurt to come to a complete stop and the go and make the turn around

No would don't need to let out till the end, take it out of 4x4 sometime down the track and like I said pratice with the truck first on the street with a boosted launch and when you get to the point where your roastin' the tires back it down, because that is going to be hard launch on the track and that's where you start to break things

You can lower the tire pressure and launch a little harder w/o spinning. I was spinning with 35 psi and i dropped er down to about 22lbs and no more spinning.

If you can go to the test and tunes and i started launching at about 1500 rpms to about 2200 rpms. But I tryed it the very 1st time without boosting to see what it was like.
