I'd bet he's running an automatic, truck is in gear with the brakes on. Needs time to heat things up so the turbo will spool..........

What Is a Trans Brake?Available for most popular automatic transmission applications from companies like TCI for between $400 and $500, a trans-brake conversion consists of a few (reversible) case modifications and a specially modified valve body that's equipped with an electric solenoid. A driver-operated pushbutton triggers the solenoid to move a shuttle valve, causing the transmission's hydraulic circuitry to engage First and Reverse gears at the same time. If this sounds like a recipe for self-destruction, remember the car is not in motion when the activation button is depressed. With the transmission input-shaft effectively locked, the driver then mashes the accelerator pedal to the floor, giving the torque converter no option other than to slip until its absolute stall speed is reached. When the light turns green, the driver releases the activation button and the car explodes off the line. Once moving, the driver upshifts the transmission in the usual way.
