2008 Mustang GT Tuning Help

[Technogod]

I decided to break out my Predator Tuner and do a WOT Tuning Session. I have a AIRAID (Roush) CAI and a Corsa Xtreme Axle-Back Exhaust. My Lambda is .81 at WOT. Do you think that is too rich? I've attached links to videos of the tuning pull. https://youtu.be/ZBWJMDRI7xU and https://youtu.be/AgRkdNgmv3I

is that commanded lambda or Lambda from an AFR sensor?

[Technogod]

It's commanded lambda. That's a really good point. I probably shouldn't be making adjustments without an AFR sensor. Correct? I switched from synthetic blend oil to full synthetic. I was amazed at the power it unleashed from this engine.

[mikel]

yeah, commanded should be close to actual, but you never know. ALso too hard to say if its rich...was this after expended WOT where it was likely in Cat overtemp?

[Technogod]

Lambda stayed at .81 until I released the throttle and then it went to 1. To be honest with you. It's running the best it ever has. I'd be afraid to change anything without putting it on a dyno. I'd love to put on some sticky tires and take it to the dragstrip. Unfortunately, my wife would kill me

good deal, let it eat
