why not?
it has to be tuned for a dry shot coz u need more fuel to be injected to stop it leaning out.

but with a wet shot of nos the extra fuel is mixed with the nitrouse in the fogger and its all sucked through the throttle body pre mixed

Yeah that's ok. Wet shots are very simple and prety safe. U can put a wet shot on pretty much anything without tuning or doing any other mods.

But correct me if I'm wrong.

you also have to have your car tuned to suit the nitrous when you arm the nitrous it plays with your timing so you dont detonate your engine

Personally I wouldn't bother with an underdrive. The only reason I fitted 1 was because it had to come off to put the cam in. It isnt worth the $$ and time to fit to gain maybe 5 rwkw. You would be much better off getting the car tuned and set up properly on the NOS. Also with a wet sys make sure you REGULARLY check your leads and plugs cause a NOS backfire isn't good.....
