For those who have done the s5 UIM onto the S4 LIM
I have done the S5 UIM ontop the S4 UIM, used the s4 throttle body. Runs great and all but do have a question on the idle adjustment. Can you who have done it get the idle below 700 rpms? I have my idle at approx 750rpms but cannot get any lower adjustment as the idle screw will not turn down anymore. I am curious if its due to the different pathway provisions for vacuum/MOPair/idle air on the throttle body and on the s5 plenum/s5 throttlespacer(black thing) or some tiny vacuum leak becuase I am using a federal s5 intake with all the extra vacuum nipples(extra ones plug tightly, i hope)
Thanks

mine idles at like 700-900 since i took the AC/CV off when i put on my road race header. it wavers.
im going to restate what has already been said. 750 is stock warm idle. why do you want to adjust the screw lower?

I still don't understand why the idle needs to be or should be or should be able to be lower?
I get it now! He wants to know what's the lowest and highest possible idles are such that he can confirm that his idle screw approximates that range.

Since they are different, I wanted to make it clear if it would affect my idle adjustments or if I just have a vacuum leak somewhere else.
