Had my vivid Air returned under warranty by SRAM but they’ve sent an ML instead of the MM I sent them stating that it is more tuneable with the frame.
What tune shocks are you guys running?

Pretty sure mine’s MM
Vivid air has behaved itself pretty well for me on the XL 601. What failed with yours?

It was knocking on rebound. Known issue apparently but got a nice new one now.
Spoke to TF and they confirmed that an ML should suit the frame/linkage design better..
Fitted and out for a ride so guess I’ll find out

Standard MM on mine, you could always drop Liteville a message about it.

Well, 1st ride impressions are really good. Used my base settings from the MM tune (slightly higher air pressure) and made a couple of rebound/compression tweaks on the way round.
Doing a very similar route to compare, the ML was a fair bit quicker (up and down).
I did ask Liteville about an ML tune a while ago, as a Vivid coil I was looking at was that tune, but they never got back to me.
