air fuel ratios

What are acceptable air fuel ratios for a 3rd gen with Pettit cold air intake and Racing Beat cat back. My results are posted from a Dyno dynamics load cell dyno.

thanks, Jim

Yikes, under 11.0?&nbsp That's a tad bit rich.&nbsp Typical ranges are 11.5:1, but you can go down to 11.2:1 or even 11.0:1 if you're paranoid.&nbsp Under 11.0 is losing too much power...

Let me guess, stock ECU? The stock FD ECU runs extremely rich. Your a:f is acceptable and you could add a lot more mods with your existing fuel/ecu setup as long as you keep your boost under control.
