1) When you're ready to go/are staged. put the truck in NEUTRAL.
2) Put your foot on the brake, and push it down VERY HARD
3) While holding down the brake, rev on the gas pedal to around 3500-4000rpm a couple times. This will create vacuum pressure, and will allow the brake pedal to sink a few inches further (usually to the floor) for a better hold.
4) While holding, slowly get on the gas to build boost pressure
5) Watch your boost gauge (your aftermarket one is better if you have one) When it gets to around 5PSI or a bit over (don't go too high or you will break your propshaft) Let off the brake while simultaneously flooring the gas.

STOCK48, Post a screen shot of what kind of timing you are suggesting ...
hell, it don't hurt to ask.

Syty with two step is what you need. The two step cuts your power in half and let's you build more boost until you let off the brake. I have made as much as 9 psi at 3600 rpm like this.
