I finally got my Cobra on the dyno this w/e at the NMRA race in BG. The #'s seem to me a little down for the boost I am suppose to be running (19#'s). The reason I say "suppose to be running " is, my boost guage wasnt working and I could not tell what is was actually making.

I am running the KB with the 9 inch lower and the 3.25 inch upper. I only made 2 pulls and they were back to back. The better of the 2 being the first which was 561rwhp.

I seem to be having a problem with the car running very rich between 4300-5700. Has anyone got any ideas what could be going on?

Here is the chart.
