Are you wanting to log boost on another device like a laptop or just within the AVCR? When I data log a pull with Nistune and my AVCR, I just set the monitor screen on the Avcr to hold the high limit. After the pull it will show the max BAR that was achieved. It sucks that it is not in my Nistune display, But when I save the log I rename it to include the psi/bar that was used on that pull. I really wish that Nistune could show the boost levels!
