Ive always wondered how useful these are on old tecknowledgy diesels. The principle is that you can raise or lower the boost at will which is great for making a high performance turbo petrol car run flat out on the track but be gental enough to drive home afterwards but in a diesel they always like as much air as you can feed them ie set as high as you can and leave it there
Sanding your knuckles before starting work can help. That way you cant skin them
