I thought a wet shot is not good for a twin screw because it messes up with the rotors???
If you are going to run a dry shot you have to have a separate tune for when you spray. As, the original poster said he had a flip chip. Wet is really easier since you can tune it with the jets and a wideband instead of paying 400$ for dyno tuning a dry shot. And then buying huge injectors to support 700 hp. Spraying a dry shot on the same tune as your blower runs is just stupid and is why so many guys burn down motors on nitrous.
The problems on a wet shot are when guys spray at too low an rpm. Under 3,000 rpm and you are asking for trouble. This is when you get backfires that blow apart manifolds and start fires. Also, you should have a window switch that only lets it spray from like 3k-6.5k. This way if you miss a shift and hit fuel cut the nitrous doesn't keep spraying. This would be like running an untuned dry shot.
A KB on nitrous on and 03-04 Cobra would be so nasty and with a 100 shot would easily make 700 whp.
You dont need nitrous
