Is there any way to reduce wastegate rattle?.. Just installed BMS downpipe and all i hear now is wastegate rattle lol.. It is obnoxiously loud with stock downpipe you can hear them between shifts now it seems to rattle the whole damn drive lmao.. It will go away under load but any other time, just a loud rattle

Assuming you have JB4:

See wastegate rattle fix jb4 here

"Default Wastegate Position (DWP): Menu 10 (0-5000rpm) & DWP under user adjustment. This setting determines the rest position of your wastegate. The default value is 3000rpm in menu 10 (shows as 60 in the JB4 interface). Higher values can make the car feel more responsive but in some vehicles will make it more prone to "wastegate rattle". Lower values of say 800rpm are sometimes preferred to reduce rattle but might make low throttle feel more sluggish. Wastegate rattle is a hardware problem in nature and the software settings can only attempt to mask this issue. In some cases no setting can fully mask the rattle. This setting only effects performance at mid to low throttle.
