I would sell the dry kit. Wet kits are much safer. A wet kit won't puddle in the intake if you use the right safey procautions. You shouldn't use the dry kit because it relys on the computer and injectors. Just my 2 cents.
Which is the reason you spent over $1k on a kit. You did pick a nice kit however
I don't feel that a car needs to be on the dyno and tuned for a 75 shot. If pughman goes a step colder on the plugs he'll be fine. It's also important that he isn't using the bottle every time the car is cranked.
I ran a NOS 75 shot on my car for quite some time and never had a problem with it. Stock tune also
