Nitrous kit with no tune?

[Cobra700]

Did a search and didn't seen anything concrete but toying with the idea of installing a nitrous kit. Probably run a 100 shot or maybe a 125. Trying not to flash the ECU yet just in case of warranty reasons. I was looking at the ZEX Blackout kit and the Nitrous Express kit with the TB plate.
You guys think it'll be safe running it on the stock or track key tune? Any preference between the kits? Thanks!

IMO anything more than a 50hp shot will require colder plugs and a tune to pull timing. That's what I've heard/read from pretty much every source.
