Leaving in 4 Hi is the only way to get a decent run, that or Slicks, put it in 4 Hi, Bump in to the Prestage light (top bulb) Hold the brake and build some boost and then bump in to the staged light (both top bulbs will be on) WAIT for the tree to activate, When the tree starts down hold the accelerator to the floor, realease the brake and leave on the second yellow, if you wait until green your way LATE! Have fun!

I actually do kick my back out of 4wd, tried it both ways though and doesn't seem to make much difference at he big end but I can guarentee you it makes a HUGE difference at the start. tried a 2wd launch, my et was .600 slower and my 60 foot time was about the same slower a 2.560 60ft vs averaging around 2.0# with 4x4 launch, what this tells me is having it in 4x4 isn't costing as much at the big end as you would think.
One note though, I am running 1/8th mile not 1/4, might make more diff in a 1/4 mile track IDK.

Also if you are still running the stock auto hubs, make sure you manually lock them. Relying on the vacuum lock when drag racing will significantly up your chances of destroying a hub. Turn them by hand to the lock position to keep them living longer.
