how do you leave the line at the track
 

im taking my truck to the track for the forst time next weekend and had a few questions. i plan on leave in 4 hi and doing a boosted launch. what should i spool her up too. should i have any concern about launching in 4hi. any other tips or comments are welcome.

Start low and work it up, Around 8-10 if you can keep traction keep going up till the tires start breaking lose. Just know how ruff bosted launches are on your truck.
