Default Does Changing Solenoids mean Changing Jets too?

I got a good deal on some NX Lignthing pro power carbon fiber nitrous/gas solenoids so I'm going to use them in my current nitrous system. It is a HSW ls6 plate system. Just wondering if I need to change the jets for the bigger solenoids or if the current jetting will have the same result?

I think it won't matter, but I just want to be sure!

If you are using the same injection device, you should not have to change your jetting.

Not always true. If the OP is going from a .093 HSW to an .093 NX noid, then Grant your right, that difference isn't going to make any noticable difference.
However if he is jetted at say...150hp or a .062 jet and is going from an .078 noid to a .125 noid, then I gaurentee that he will need to change his jetting after swapping noids.

If the solenoids flow different than you will need to change your tune up.

I am going from .125 HSW nitrous solenoid to a .125 NX nitrous solenoid and a .250 HSW fuel solenoid to a .310 NX fuel solenoid. What exactly do I need to change?

Vinny brought up a good point... To add to that if your solenoid was having issues opening all the way ior it was flutering it could restrict flow.. There for switching to a solenoid that may not have that same issue could change the amount of flow causing a tune up change..

Best to double check just to be safe..

Fuel jetting will definately change... Nitrous "should" stay the same. You need to verify both by pulling the plugs after a pull...

So jet it/tune for a small shot, verify everything, and go up from there?

You think if I just start with the normal HSW jetting for a 100 shot and go from there it will be alright? The worst that will happen is that I will be a LITTLE rich right? After that I could just use a smaller fuel jet or a slightly larger nitrous jet depending on what the plugs say right?

Yes start with the recommended jetting first.
