question for those who have the single turbo setup
 

Okay for those of you running single turbo its a absolute to disable the ICS? The idle control speed that is? I finally downloaded the manuals but I can't find out how to disable it only adjust it.

(1) unplug the ISC
(2) if you have a PFC, turn off O2 idle control
(3) if you have a PFC and DATALOGIT, set idle speeds to 0 (allows idle timing control)
(4) open manual throttle adjustments to keep engine running

I've been living with the rough idle on my car for a while, and I think I'm finally gonna go and do what Chuck suggested (and what's been suggested for a while on the forums). I've been doing lots of searches, and I think one thing that should be added to what Chuck said is that you should use the manual adjustments to set the idle to 900 or so WITH electrical and A/C load to prevent the engine from dying when you turn on the lights or AC.
