1. Put the transmission in (N) Neutral.
  2. Rev the engine while simultaneously pushing down HARD on the brakes.
  3. The brake will set a lot tighter because the engine will produce more vacuum assist.
  4. After doing this for a couple seconds the brake will be as far down as it will go.
  5. Keep the brake all the way depressed, and shift the transmission into Drive (not Overdrive).
  6. Start pressing on the gas pedal now to build up boost.
  7. When the boost is where you want it and it is time to go, release the brake and slam the gas at the same time.
  8. Typically, boost levels of somewhere between 0-5 lbs is good. Try launching at different levels to see which works best with your truck. You want a little chrip from the tires but not a lot of wheel spin. With a stock truck it's difficult to get a lot of wheel spin, but with Recipe #2, it's definitely possible.
