you need to do it with the truck running... turn the fuel screw in 1/2 turn at a time and rev the engine after each 1/2 turn... if you are close to "runaway" your RPM's will not come down immediately and you should turn it down 1/2 turn from that point.
take the intake tube off of the turbo 1st, and have something (a board preferably) to block air from coming into it. that will shut down the engine incase you get too carried away and the engine runs away.
