My guess is somewhere in the 365-372 range will be optimal. On bigger cam cars you can get away with starting injection even earlier but stock cam stuff doesn't gain from it as Mike mentioned.

FWIW - I have read this thread several times, and you comments, too
Where I was coming from what just that not knowing what, if any, effect the PI had on what the E92 was trying to do, and since, my calculator was showing I was safe- EOI-wise, if SOI starting before TDC would be a problem. It seems, by what you guys are showing, is that it must not be, because you're making more power starting just before, and I'm, perhaps, just outside of your-guys' envelope of data. I've gathered I shouldn't gain in power, but I'm just looking for RAIL PRESSURE/IPW to come under good control. I read Huggins or Higgs saying to command, like, 280 and leave it, because the ECM will compensate automatically anyways, but I just didn't know which way to start. That was a couple year old post, and understanding changes with time, so I'll go with the current logic, here, from you guys.
I did notice my adder was adding about 15* of timing, and I was going to pull out a handful, but I think I'm going to try what you suggest, and see what happens. I'm SO CLOSE to wrapping this up the way I was hoping to I can taste it. I'm only a stock cam, and I'm only trying to make sure it's safe and hopefully be reliable.
