I understand they're ubiquitous in the modified world but they're literally the only codes I have issues with and a hinderance to emissions. 3.6 turbo that does well in every other realm and with them switched off, life is good until I turn them back on to deal with emissions. I've played with airflow delay tables in the past with no change and I'm going to attempt to pick that up again but not yet convinced that will even do much.

Would appreciate any intel, thoughts or experience anyone would be willing to share to learn more. Thank you
