AFR's for a relatively stock 2007 yukon
Curious if anyone knows the sweetspot numbers for AFR at WOT for the 5.3 in a 2007 Yukon? All I have is an Airaid JR CAI. I have a diablosport trinity now and plan to do some logging. Once I have my logs, I'm curious what a good range is for WOT on these trucks/engines as far as my AFR's. I'm not sure if AFR's are typically the same across all engines and brands in what you actually want for best performance. thanks for any and all input. Sorry if this is a stupid and/or rookie question. Cheers.
