I have a 2013 Fox Float CTD BV which came with my Mega frame. After the first few rides I noticed it would always sit too low and blow through the travel, even with sag set correctly and what seemed like the correct pressure. Rather than dick about with the air can reducer kit I decided to get it Push tuned by TF and it honestly feels like a different shock now. It sits higher, tracks better on the small bumps and somehow feels bottomless when the going gets rough. No pedal bob either. There is also now a noticeable difference between C, T and D modes, although Trail now seems perfect for 90% of what I ride.
So yeah, I’d go for a custom tune 🙂
