I used an Efilive custom operating system. (COS5)
Tune in SD as normal. Add a pin to the pcm that switches to earth when spraying.(J2 pin 56) & calibrate the nitrous tables. One table will adjust the VE to add fuel for a dry shot, another table is utilised to pull timing.
Using a stand alone wet system you would only need to populate the timing table.

I have my own copy of HP tuners and had my tuner make me two tunes. I pretty much know when I am going to spray so I will load in that tune when the time comes. Otherwise I am on my street NA tune.
I tuned the map to be on the lean side at 90 95 100 kpa and let pe fuel at wot. If its a wet setup tune fuel with plugs, fuel pres and jets. My car likes a 180 shot with 12.3 AF, pullin 6* on an 8 plg.

COS 5 uses a 2002 LS1/6 Base tune and attaches the custom operating system (tables) to that.
If you cant run the 2002 tune on your PCM COS 5 is a no go.
I was able to use the 2002 tune w/ my 99 PCM, but I had to paste the matching 99 table values to 02 tables, and had to work around the tables that were different or none existing.
Up to 99-04 PCM's should work w/ Cos 5 I believe, LS2/3/7 (1024k+ PCM) Cos 5 will not work.
Enough interest @ EFI live and maybe the EFI Live boys will make a COS for the lastest PCM's. Last year I remember asking for a COS for LS2's but I do think that happened.
