i had my pal turn the boost down on my saff,i now want to wind it back up to what it was.the Q is how do i do this via the actator arm,my mate says screw the nut on the arm to shorten the arm in small turns and test and repeat until the correct boost level is achived,is this correct as i heard somewhere b4 that you have to take the actuator off to adjust it?? cheers all
