I'm wondering what you guys are running at wot and I didn't know that the number the wideband says on the dash is lower than the tailpipe which is what most dynotechs use.

 

I believe your question needs some clarification. Are you looking for naturally aspirated AFR, forced induction or both? There is going to be a difference.

A good tuner will look a the data logs and not read AFR at the tail pipe. Ideally using a stand alone AFR meter with a serial connection on the leanest bank will suffice nicely or you can use the readings from the factory sensors.

 

Supercharged cars need to run a little richer than NA. I ran my Vortech'd '07 GT around 11.6:1.

 

Both my bama tunes run at 11.7 and I thought that was lean but brenspeed said that was spot in go figure

 

I thought lower number meant it was leaner not realizing it's the other way around

 

both but u was reading my afr wrong anyways

 

11.7 for a naturally aspirated engine is a bit on the rich side actually. For the 11-14 Mustangs, we usually like to see in the 12.0-12.4 range. 11.7 is the sweet spot for light boost or nitrous applications!

You should get in touch with the Bama Team and send them a few datalogs for review. If your AFR's are truly at that point, than I think you could benefit from a tweak in fueling and pick up some more power.

If you've never datalogged before, here's instructions on how to do so. Make sure you zip the datalogs into a file when sending it to the Bama Team too.

Hit me up if you have any other questions or concerns!
