2001 Running Rich

Postby GeorgeS391 » Sat Aug 31, 2013 11:28 am

I've got a 2001 Miata with AEM intake, Roadster Sport Cat and exhaust and Racing Beat Muffler. I just got back from a dyno session and it seems the car only makes 120HP and runs rich above 4500RPM. AFR is around14 below that but drops to almost 12 above 4500, all the way to redline. Roadster Sport Cat is the latest add-on I've done (above 2 months ago). I have noticed that the mpg is down, but thought that was just caused by my foot on the gas so I could hear the nice sound of the new exhaust. Looking for any suggestions on how to get the AFR back to normal levels and hopefully getting more HP out of the car.

Suggestions???
