Whats the LSA on the cam?

If you don't get 500+ you should be close.

Not too shabby, looks pretty rich from 4-5.5k. Add a little fuel up top for around 12.7. See a little squiggly at redline. Maybe some valve train instability.

Overall a VERY flat tq curve. :-) Looks almost electric.

Huh? I don't see too rich? It looks to me that his AFR is over the 13 line up top. I would do as you say tho and get it down around the 12.7 range. That'll pick it up a lot I would bet. And that dip around 5k should have been fixed by the tuner I would think.
