OK, I have had this gun for about a year now and am considering tearing it down and doing a tune on it myself.
I have looked thru the library here and found some tutorials for stringers with photos but can't seem to find one with a nitro piston.
Has anyone done a tune on a NP and documented it or know where I might find one?

Kevin, before you get going on your project, have you determined the FPE you are getting from your gun? My advice: if you have 14 FPE or better from your stock gun, don't bother with the tune because there's no guarantee that in the hands of a casual or even novice tuner you will get better results after your tune.

Since you're in Canada you may not get 14 fpe, unless it's a fac version. The gas strut version comes apart just like the steel spring version, you just don't have to worry about some of the details relating to the spring.
Before beginning the tune process try to lay out in your mind EXACTLY what you expect from a tune and what you are trying to improve with a tune.

That is correct, although i have not shot it through a chronograph I am nowhere near 14 FPE. I just want to go over it, remove any burrs or rough spots. Just a general clean, lube and replace the stock seals.

the NP Trail is easy to work on but as other have suggested, you might want to chrono test it BEFORE taking it down.
IIRC, the UK has a 12fpe limit before it goes into 'firearms' category; a simple tune could possibly put you over the limit.
