Dyno Graph- Renntech Stage 5
Recently had my car dynoed. I have been more concerned with the A/F ratio as my A/F ratio was getting too rich up top which I believe was limiting my horse power potential. Can anyone comment on my A/F ratio? It looks better than my previous dynos in my opinion. Not sure if it is near perfect yet though.

Steve, have you contacted your local Renntech dealer? Also, can you enlarge the dyno chart? I have a problem seeing it.

Kinda interesting. My local stage 5 Renntech has a lower torque number than yours but has a higher hp.
Let me try to find my dyno charts.
Who did you talk to @ Renntech?

My car was still hot when I ran it? Noticed that when I run it while hot my hp reading changes, but the torqe stays the same. Will post another dyno chart that illustrates this.

This chart has 2 dyno runs on it. Notice that on my 2nd pull the car only put down 471 hp. This was after 3 consecutive pulls and the tech and I finally realizing that the car was in S as opposed to M. In the 3 prior runs we couldnt keep the car on the dyno machine as the transmission would shift down from 4th to 3rd gear and the car would go sideways on the machine.

Perhaps the A/F ratio on your dyno is a little on the "safer" side? If you want every HP extracted then sure 12:1 would be great but a little rich on a forced induction car with higher boost can buy you some margin for error.
