I was dialling in the cams the other day and was a little shocked at the result. The duration of the inlet cam is 15 degreees more than spec and the exhaust is 20 degrees more than spec. I have a second set and they were out too but not by the same amounts. All cams are original and have noe visible wear. It goes to show that in mass production these motors are just thrown together. Anyone else seen similar?? The other thing for the turbo guru's out there. how much should i advance/retard the cams.
