Thinking bout running a 100 shot!!

I dont know if the brand of kit matters, but get a wet system for sure if you want to run a 100 shot. A tune would be a good idea, or should I say almost a must to make sure the AFR is good, and I think you need to back the timing off for the nitrous as well.
 
You don't need a "tune," but I would back the timing off a few degrees. The beauty of a wet kit is that you can get the a/f where you want it using fuel pills.

I've been running one for 2.5+ years, no problems. I backed the timing off 2* global and got the a/f in the mid-11s, no problems at all.

Go with a reputable wet kit (NX, ZEX, etc).
