Hmm. Well, the track was only at 70' elevation, so I can't imagine that correction would have thrown stuff off too much. But good to know for the future.

The Superram is waaay better than TPI, but it isn't meant to rev high. On a 383, everyone I've seen is shifting in the 5000-5500 range.

Did you tune that with a dyno, or have you tweaked it with trial and error at the track? I think mine could take a bit more timing, but on the street it's hard to see if changing timing or fuel helped or hurt. I'm also a bit paranoid about knock - as a newbie, I am not familiar with what it sounds like (I've watched videos, but it's not the same). I've been getting lots of knock counts at lower RPMs which I've attributed to false knock, so it's hard for me to tell if knock counts at WOT could be false knock or if it's the real deal. I don't want to risk adding in timing, datalogging a run or two, and hurting my engine from detonation.
