Hi guys,
Looking at getting the RP23 on my nomad sorted - its a 2012 kashima on nomad c. The can has 175 boost pressure, low compression tune and light rebound.
It blows through the midstroke all the time and generally performs badly given my weight (almost 16 stone kitted up). I spoke to TFTuned and they reckon getting it PUSH tuned would help a lot - cost £139. Also spoke to mojo who said they can revalve it for £36 and that this was basically what a Push tune involves. Why is there such a big difference in cost? What else is involved during a push tune other than a revalve that justifies the extra hundred pounds?
Thanks
You could also try the Fox Air Spring Volume tuning kit where you can add inserts to the air can to tune the shock. They might do the trick for you as with a reduced air can volume the shock should be less inclined to blow through the mid stroke as the pressure ramps up I would imagine.
http://www.mojostore.co.uk/acatalog/Air_Spring_Volume_Tuning_Kit.html - seems to be out of stock at the minute.
Sell it and get a coil. Worth every extra gram IMHO.
I would be tempted to try an air shock again but it will not be a Fox one.
Ring and speak to TF - Dave if you can, he'll explain the difference.
PUSH tune has a different piston and shim stack to the Fox retune which will use the orginal piston and change the shims stack to get different tune levels but as per Fox specs really.
I vary what I do to shocks with my tunes depending on model year, bike etc, using the orginal fox piston which is sometimes ported or PUsh pistons if fitted.
Different tunes get different results. This is a pretty in depth subject that would need an essay to explain fully tbh.
as loco said push uses different internals, which have to be purchased and fitted, for a re-tune a mechanic just fannies around* with what's in there already.What else is involved during a push tune other than a revalve that justifies the extra hundred pounds?
No idea which is better.

😆 How VERY Dare you 😯 😆
It depends what you would like the shock to do better really as to which option is better, and how much you'd like to send 😉
TFTuned did me a Push tune on a coil shock after I gave them a detailed background of how I felt the bike rode in different situations and how I wanted it to ride differently. It seems to be absolutely mint but I need more time to ride it in different places to see if it ticks all the boxes and decided where the compromises are.
They talked me through the method they used to dyno it for a baseline, then mod it and then re dyno a few times while making tweeks to get the damping profile to corrospond with my wishlist. They were very helpful and admit to where they put in the guess work and experience as the dyno is not the be all and end all but a very good tool to account for different linkages etc.
A big tommy two thumbs from me 
but £139 against £36 pounds makes it a tricky choice for you. I would try spacers first as a very cheap reversable option. 🙂
the mechanic using their indepth knowledge and honed skill carefully manipulate the complex damping system to change the shock's behaviour.How VERY Dare you
that better? 🙂
I tried to contact you from your "contact us" page loco, concerning some of the aformentioned fannying around, couple weeks ago no response tho - I also enquired about the pic on your website.
oh just thought, didn't check spam folder will look later.
