Unless you want the forks to perform differently to how they currently do, having tried the different adjusters etc there is no point having them “tuned” if you just want them as new a standard service will do and don’t bother with the revalve (tuning)
From personal experience – mojo tuned some 36’s for me when I was younger and didn’t even bother to call me to ask what I wanted, they did the same last year when I sent my CTD cartridge for an upgrade – but I’m abit older and wiser now so told them to explain how they have custom valved it without taking to me…
Tftuned did a push’d dhx 5 for me – the guy doing the work rang me and asked all sorts of questions and gave me options. So they’d get my shout.
On the other hand if they need a service and your willing to pay the money why not attempt it yourself?
