You need to post vehicle info. I'm assuming '88, so S4 FC? The ACV has nothing to do with the aux. ports on an S4.

its a 90 gtu s5.so i know i dont need back pressure but im just not sure that if i remove the acv i will need to set it up differently

Do not remove the ACV or airpump on an S5 NA. Your aux. ports (6PI) and VDI are fed air via a nipple on the ACV near the air pump outlet.

whats up with removing the aux valves so it always open whats the good/bad?

That's a pointless "modification" people do that has no benefit and costs low-end torque. There's a reason the 6PI and VDI activate when they do.

ok so i just ordered those atkins rotary aux port sleeves without the dead spot like the stock ones, im curious if when installing my LIM should i grease or lube any of the moving parts suck as the port sleeves or the actuator valves etc;
