How big of an injector would you need for a 2000 SS M6, TSP 231/237 cam on stock heads, longtubes w/offroad Y, TSP lid, LS6 intake, cutout and a TNT 125 wet-shot.

If you plan on keeping it there, i would go with maybe 36 or 42 max. The wet part of the shot takes care of a lot of fuel. A 42 size would maintain a good idle and still leave a lot of room for future mods.

The wet shot should be jetted to give you the fuel you need with the nitrous. The injector size depends on what horsepower output you got without the juice on and what altitude your running. There is a formula to calculate size for given horsepower. The fuel pressure going to injector can be used to allow an injector support higher horsepower engines. Be careful of going too high on the pressure, as the higher you go the harder it is on the injector to operate. So keep it under 50psi and I'd guess 30lb injectors would do fine for your app. Just make sure you got a good strong pump to support extra flow when nitrous hits. Call TNT and ask them if your pump can keep up. make sure there is a good solid 12 volts going to it to. If you change injectors and/or pressures, make sure you tell your PCM that or it won't know what the hell to do.

with a wet shot you might be ok with the stockers, 30lbers would be nice though.

Do you guys think a set of 37's form racetronix would be too big? They dont cost that much more than 30's and I'd like to have some head room for the future if I add a set of heads.
