Obtain more hold on the line for better
boost build up and take off.
Disadvantages
None, just be prepared to hold on.
Procedure:
Put the transmission in (N) Neutral.
Rev the engine while simutaneously pushing down
HARD on the brakes.
The brake will set a lot tighter because the engine
will produce more vacuum assist.
After doing this for a couple seconds the brake
will be as far down as it will go.
Keep the brake all the way depressed, and shift the
transmission into Drive (not Overdrive).
Start pressing on the gas pedal now to build up
boost.
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.
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.
