Alright, lets get down to it. I'm looking for power. Given that, which is better, a little richer and more ignition timing, or leaner and less timing? Currently I'm working toward the latter, but want some input from some that run fast.

Also, which is better for spool, lean or rich. I can't get my pre-boost #s into the rich range. If I do a 3rd gear pull from 1500-6500. My O2s will read .08 until 3500 or so when they jump up to .8 and then .9 around 4000. My setup is working, but I want it to be the best it can be. I can post up my SAFC settings if you guys want too. Their F'd up.

Really?!? Is that 1G or 2G? And what about the knock counts? I may just have to start tuning a l'il differently


Well they also usually run a standalone. There are several of them running around on DSMtalk. What I do know is that you want maximum cylinder pressure around 14-16 degrees after TDC. Higher boost is going to make the charge burn faster and therefore need less ignition timing to make that happen. That being said, there's just as good of a chance of me having my settings perfect right now as you guys running 20 any other number and having it happen. I guess what it all comes down to is that I need some dyno tuning to run perfect.
