Putting her on Dyno Sat....have a question

What should my air/fuel ratio look like?
I get 2 runs w/ O2 sensor.

This is the first time ever putting a car on the dyno. Is there anything else I should know/do?

Thanks.
 
Only did one run on the dyno cause I was too lean--- 247rwhp, 326rwftlbs, going over 14:1 a/f ratio at 4400 rpm.

I got home and checked my fuel pressure, and it was at only 30psi! I adjusted it back to 40, so now I should be good to go. Somehow it must have loosened up from when I set it last year (39 psi). The guy can also burn me a custom chip from Diablosport. Between the chip and my increased fuel pressure, I'm hoping for 280, 350.

We'll see in a few weeks.
