The Push tune from TF tuned made a huge huuuuge difference to my NP Mega’s Monarch. Night and day, it was a bag of wallowey yet unresponsive shit before. It would dive into it’s travel but at the same time wasn’t very sensitive to small bumps, to get just some grip I had to bump the rebound adjuster up so much that it had an unnerving tendency to bounce around through hard hit’s. So I asked the guys to service the shock and give me a firmer, poppier shock with a slightly faster ending stroke rebound.
The push upgrade included a higher flow piston and a few other bits (I think) which reduced friction and allowed the TF tuned guys to play with the shims, something about the standard version that makes the latter a pain in the arse.
The TF guys went with a whole different approach compared to loco, they upped the compression damping (instead of using the spring rate for support) as much as they could before rear grip was compromised and bumped up the ending stroke rebound. They sent me a few internal volume spacers and said I probably wouldn’t need them….I didn’t…and despite the aggressive compression tune the shock is more supple than ever.
