  • I know that lately, we've gained a lot of new members which is awesome and a lot of those new members are coming from other forums that may use vBulletin and their Private Message (PM) system. Here, we use the XenForo forum software which is (IMHO) much better than vBulletin. The "Conversation" system here is the same as the PM system on vBulletin. So if you want to PM another member, just click their username in a post, and click on "Start Conversation". To see all of your PMs, click on your profile and go to Inbox. Hope this helps.

Condition
There may be a concern with a rattle or flutter noise from the supercharger tensioner and belt. This occurs in V4 mode with light throttle conditions. Issue sounds like tick noise when in driver seat.
This seems to vary between vehicles but replacing the tensioner won't resolve the issue.
Cause
The supercharger belt tensioner will jump and cause the noise
