Optimizing WOT P/E and spark My car runs pretty good now. I got my VE and maf under control and everything seems to be goin well.
I have a full bolton m6 LS1 (Lid, Smooth bellows, Ported TB, SLP MAF, ls6 intake, long tube headers, ory, exhaust)
also it is cammed with the torquer v3
231/234 .644/.598 111lsa
Currently for P/E I have:
0-3200 12.8 then it blends to 12.6 by the time it hits 5600 and stays there till redline of 6700.
For my spark table:
I believe i took a 99 spark table (heard it was a bit more aggressive) and added some spark at WOT, then just took a little away in a couple areas with KR and smoothed.
I am netting: 26-29* Advance at WOT
How do i know what is optimal without a dyno? Any suggestions you can recommend? (I hope to get dyno time eventually but I don't have access to one yet)
Anything i should be concerned about safety wise?

you really cant tell if it is tuned optimal. you could just go to the track and see what it runs for mph but there are a lot of variables that come in to play. I would say you have it tuned safe right now.
26-29 degrees sounds fine to me. put her on the dyno and see what numbers she gets at various sparks. i noticed that my car likes it richer down low, say 12.5 and then leaner up top. In the low RPM you have more time to burn MORE fuel, so you can have extra fuel down there, in the high RPM you have less time to burn fuel, so take out some. i think you are kind of doing the opposite of that
i'd slap in a 12.5 or so down low and run up to a 13.1 up top. **several cars i have done seem to like it around the 12.9~13.3 range up top with 26-28 degrees
to really play with it you will need some time on the dyno, and that will get you a LOT of exp tuning also
