Hi,
When I got my car dyno tuned, the side exhaust was open and it had off-road H-pipe and muffler deletes.
The tuner showed me the A/F hovering around 11.5-11.9:1
I closed the side exhaust and put the GT500 muffs back on and my Torque app is reading 14.5-15.0:1 from the ECM.
Here's a log entry from Torque

I was under the impression that A/F ratio above 12 is generally bad. Any ideas what might be going on here?
Also, is it bad to drive it under this condition?
I have larger longtubes too.
