Yes I am using the old chain still. I read that attachment you put up. I have a dial indicator. I may do this 2mm lift method tomorrow if it looks easy enough to rig with the dial indicator base I have. I hooked up the turbo, I just need to do the line to the back of the filter tower. What do you think about putting some rubber bicycle inner tube around the clamping points for that turbo line. I was thinking of maybe sandwiching some in there to avoid the line getting worn through as I have heard can happen.
