Default Dyno Numbers are in.

OK. Unfortunately something wrong with the Dynojet software or I'd post the graphs but here's the story.
Bottom line is motor made a max hp of 387 rwhp. Max rwtq was 356 but this was not on the same run. On same run was 386hp/356rwtq.
On other runs it was basically 385.xxrwhp/350.xxrwtq.
I'm not sure which calibration to use. I chose the one with more tq.
Changing AFR and some timing made very little difference in final numbers. I wish I could run the graphs, but the Winpep software sucks, or I'm doing something wrong. It looks like HP peaks at about 68-6900rpm and torque peaks at 53-5400rpm. HP curve is flat and does not noseddive. Stays within 1-2 hp up thru 7k rpm.
Numbers are SAE corrected. It was 90d at StreetStuff today here in Chicagoland. Started runs with engine temp at about 194F.
Tuned timing to where I got 0 KR and AFR was at 12.7-12.9 top end.
