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 ...

I have a 2022 Jeep Grand Cherokee Overland Pentastar 3.6L with a K&N CAI and Borla S-Type Cat-Back Exhaust. Do you offer any tuning options for this setup?

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.

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 ...

I started reminiscing about my 2008 Mustang GT today. It has a Diablosport Airaid Firm Shift Tune, Roush CAI and Corsa Xtreme Axle-Back Exhaust. Changing to Full Synthetic oil made a huge difference. Checkout this 0-60 mph run. https://youtu.be/jWfFoH8I7YY
