I had the same experience running my 2013 140mm Talas, they’d pack down under the slightest provocation and the fork would dive upon entering high speed corners or compressions and not return till i popped the front wheel.
Loco’s tip up there ^ regarding an extra 5ml oil in the air chamber is a good place to start, I’ve ended up using an extra 10ml in the air chamber, an extra 35psi in the air spring and i’ve changed the fork oil to a mixture of Redline 10wt at 132ml and 15wt at 23ml (85% and 15% roughly) ratio in the oil chamber.
I realise that fox felt they ought to make the forks simpler for your average “joe” to use with the new CTD system but some of us are competent when it comes to suspension set-up and don’t just blindly bugger about wi the set-up knobs, once set up correctly then they shouldn’t need fiddling with at all.
