With the BB backend flash + JB4 I get terrible WG rattle with lagfix below 60 but when I take the JB out it seems to go away. I'm trying to get my dealer to replace the turbos (or adjust the WGs) under warranty and I would have to take the JB4 out for the visit (already tried and failed with it in). I've tried adjusting the WGDC pre-control A table to induce idle rattle (raised it and lowered it at the lower end) and even the base table but no luck. The rattle normally occurs after letting off the throttle below 3K rpm, which table should I be tweaking? Do higher or lower than stock mappings normally increase rattle?
