IAC Counts at 0 after LSX intstall
IAC Counts at 0 after LSX intstall Like the Title says. Before the install I was around 30-50 in neutral. I know most people have problems lowering theirs, what in edit would I change to get mine to go UP?? BTW, I am using EFI live so it isn't a software bug. 
Thanks,
Chad

I did hook up the IAC sensor. I changed the settings in EDIT to reflect NoGo's idle tuning and now the IAC's are arounnd 25-30 at idle. What I dont' understand is why are my LTFT's all jacked now? At idle they are 20's but during non load and load cells they range from 0 to +6. If there is a vacuum leak, what is the best way to tell?
Unlit propane torch is one way (least messy). I would
disconnect the IAC motor and get to idle w/ a shim
between throttle cam tang and the the closed-stop.
That way the IAC won't try and hide it from you
before you can hear the RPM change.
If you get near the leak the RPM will change, drop
most likely. I would suspect either the TB-intake
face, like a kinked or missing O-ring seal (?), or one
or more of the intake-head ports - this is where I
think a lot of the Holley intakes had leak problems.
Now, the LSX is also a multi-piece design? Could be
something funny along the parting lines, some flash
or something that keeps it from sealing perfectly?
Last of all I think there's some blowout plug in the
back (all of this is fuzzy recollection from ad pix so
I could just possibly be confused) that maybe isn't
sealed up tight?
Anyway, see if you can find it with the propane...
just "paint" it methodically and see what if anything
responds.

Well guys, I am a jackass!! I found the leak. Turned out I was so happy and excited to get the intake on, it just blew my mind to hook up the vacuum line on the passenger rear side of the intake. Started going over things and re-read the directions. That was my problem. Now the IAC's and LTFT's are back where they are managable. Thats for the replies.
I also did check around the intake for leaks and had none.
