Stop yelling we can hear you, also the above is hard as hell to read, it should have been done with 3-4 paragraphs, one long sentence in caps is not going to win you any friends here.

I do not know how much help I can be, I run a 94 LS, stock innards, GSR transmission w/Phantom Grip LSD, CAI and 5Zigen 2.5" exhaust, [no cat] and a 75 shot, [dry], I use 101 octane gas and colder plugs when spraying, timing is retarded just a little, It has been working very well for the last 7 years of autocross, no problems whatsoever. 94

i'd take it to a shop with a dyno and tuning abilities, and let them tune it properly.

a lot cheaper than "home tuning" and blowing the engine...

Got to agree, even with my setup I have mine "tuned" for the track and for DD, by someone who knows what he is doing. 94

how much compression are you running? 120 shot is a lot of nitrous without being tuned for it ... even on race gas, I'd be nervous...

120 is a lot, it is a "wet" system, right? 94

As mentioned, "take it to a shop" that much $$$, time and effort into the build, I would want someone who knows what he/she is doing, tuning it. 94

I'm at 12:1 compression and I asked my tuner about putting a bottle in. He said if I wasnt going to have it tuned, I could put a wet kit in (75 shot), retard the timing at the distributor by 4 degrees, and "hope for the best" but by no means was he recommending it.
