first off, just for apple to apple comparisons, that 500rw dyno is STD corrected, that would equate to about a 480rw SAE dyno.
But even with that, those traps are awefully low. This is why I hate dyno drum racing....it's not reality. A car can be tuned to run great on a dynojet drum, but wreak havoc out on a road with a much different load factor. Your PCM could be sensing knock and pulling mega timing on the road. Only god and autotap would know whats really going on when tire meets pavement. From the looks of the timeslip, it's not panning out to no 480rw....
Now as far as your other setup items, I'm not sure why everyone keep mentioning the et street psi and low traps.....if anything, too much psi is going to actually INCREASE trap speed from the additional spinning downtrack. That is drag race 101 phenomona.
I think you need a wide-band bung welded in, a true a/f meter, and an experienced tuner who is willing to tune out on the road. You're going to realize max value that way. And, gulp, if all else fails, it might be time for a compression/leakdown test. Something could be wrong. I don't like the looks of how you seem to be slowing down really bad on the back half of the track. That is not a good sign.
Good luck!
