[Closed] Fox Triad service - Worth PUSH tuning at service?

I'm sending my rear shock off for a service to TFTuned next week and there is the option that it might be capable of getting PUSH tuned. Thanks to the way that the suspension works on the Stumpy, I can't upgrade to something better, so this is the only option I have for getting something a little more plush.

I appreciate that the rear suspension is likely to feel a lot better following the service and when it is fully workign again, but has anyone had their shock tuned in this way and was it worth the money?
