NOS Question- plugs and jets
After installing colder plugs, I noticed that my plugs seemed alittle lean. I was thinking of running a fatter gas jet and keeping the 150 NOS jet where its is. What wet system jets are other running? Is anyone running NOS on the stock plugs and Plug wires?

You need to run colder plugs. Most of the LS1 guys use NGK TR6 plugs with nitrous.
What is really needed is a non-projected tip plug. NGK makes one that fits my ZR-1 but I don't know if they have one that fits the LS1 head.
Do not use platinum tip plugs with nitrous. They will cause detonation.

I changed out my plugs to autolites. They are 1 step cooler and copper. Did anyone install their own nitrous wet system? Does the shraeder (sp?) valve just unscrew or does it remove completely?

The schraeder valve, itself, unscrews. You can use a valve puller to unscrew it OR a REALLY long set of needle nose pliers.
You can certainly go up a few sizes <in thousandths> of fuel jet. Be advised: You will lose Horsepower.
