Dry sprays just nitrous, you spray it before the MAF and the PCM adds the extra fuel. A wet shot sprays N2O and fuel, you either pull the fuel from the rail or go to a stand-alone setup. Anything under a 100 shot I'd stick to dry, just for cost and simplicity.
so if i were to buy a wet kit what upgrades would a need for the fuel system. is it unsafe to do 150 shot on dry system

Which ever route you take with the nitrous system you install on your truck, I would install just about every safety item offered for nitrous systems. Only because you are so new to it, and untill you really understand what's going on with how the system works while you're using it, you don't wanna press the wrong button at the wrong time or hold on to a button for longer than you're supposed to.
It's to the point now for me, where all I have on any single stage nitrous system is a button.
Another nice thing about a wet system is, when you run a stand alone fuel system you can have a gallon cell with race fuel in it. This way, the timing doesn't have to be so retarded.
your saying if the fuel you spray is higher octane, you dont have to retard your timing as much?
I havent done nitrous because i dont wanna mess with two tunes...
You're still gonna wanna pull some timing, but you can save yourself a couple degrees. A degree for every 50 is the typical rule of thumb. I've bumped it to a degree for every 100 when running 116 on a stand alone system, and never had issues.
My next setup is going to consist of a direct port nitrous system, and E85 as the fuel in the stand alone fuel system. The fuel will help because one, it's 105 octane and two, it is mostly alcohol which makes it run very cool. Also, you have to use 30% more E85 by volume compared to pump gas. This all equates to much cooler and ''resiliant'' air fuel charge, so the engine won't require such a cold plug and so much timing pulled. This will help alot with running a nitrous tune on motor, and not being so doggy in lower rpms.
I like it wet better.
