the only problem with nos is the solinoid duty cycle if you use it too much the solinoids over heat and fry the coil and they are expensive to replace . they are meant for a 14 second burst with a 15-30 minute cool down its mainly the gas valve which overheats as it has too control 800-900 psi.
I have had the problem where i was at a test&tune and not many people were there it was early but i did 3 back to back runs and could not put my hand on the gas valve it was so hot.
As far as dry v wet in smaller hp application not much differance dry is much easier to install .
Just be sure your fuel system is in top shape filters and pump. and follow the instuctions to the letter. and get you fuel mixtures verified on a dyno to be safe.
it sure is fun to let it rip but at $18-20 a kg you will find your self looking for extra cash to keep it full.

You cant resist the urge to purge.
