ACV Delete Idea... Prob dumb lol
I have an S4 and I have the AUX ports set up with the air pump. I want to delete the ACV, I understand most people delete the air pump at the same time, but I want to keep the functionality of my AUX ports. So, my idea is to connect the ACV relief valve hose to the air pump (Where the air pump hose goes to the ACV) so that the air has somewhere to go. Would this work? Or would the hose be too restrictive for the air pump itself?

You can delete the ACV on a series 4. Back pressure tube helps actuate the aux ports. Just buy a block off plate from Atkins or someone and remove all related components not needed after removing AVC and air pump.
i assume you have no catalytic converter and do not have to emissions test, and maybe a header?

Air supply needs to come from the split air pipe off the exhaust near the presilencer or catalytic converters depending on your exhaust setup. You can completely remove the ACV, air pump,and all the hoses and silencers attached. Series 5 relies on the air pump for several engine functions including aux ports and VDEI, but series 3 and 4 13b does not need them for much of anything unless you must pass emissions tests.
