First let me say that I hope that the graph above is just a baseline. I would hope to the heavens above that you are not running that setup daily. Your A/F is horrific. I am going to stop there because I just don't know what to say but WOW! By chance, who tuned your car? You need alot more time on the dyno. A true load bearing dyno to get those A/F numbers in check with reality.
