Upgrade on 2013 Orange Five

Hello folks, need some advise on upgrades for my 2013 Orange five 26 inch wheel

Just bought a 27.5 plus hard tail for some trail centre riding with my son and while I’m using it I fancy upgrading my old 2013 Orange five

Bought the bike new, used it for around a year then it sat in the garage for 5 years while I recovered from an injury, been using it again this year and have been enjoying it.

However the suspension is lacking, was thinking of upgrading the fork and shock and turning it a bit more gravity focussed, not overly concerned on increasing the weight

So do I get the existing set up tuned by TF or mojo ? Or do I swap out the forks and shock ?

Planning to replace the pivot bearings, bottom bracket and headset over the winter as well to tighten it up a bit.

Would appreciate anyone thoughts ?

Fork is Fox Float 32 140mm Performance Series FIT CTD 15QR

Shock is Fox Evolution Series CTD
