Got a like new 70mmTb off Ebay and a new Plenum from Brenspeed. Installed today, runs great but cant get idle down below 900rpm. During driving I can feel it (idle) drop here and there while coasting but never goes down where should be. It (little note with 2 screws) said to replace screws in " IAC", not sure but used in cylinder piece bolted toward front on the right side. Have idle screw backed out to where it isn't even touching. Any thoughts ? What does brass screw do on bottom front side of TB ? I'm no car genius but a small piece of paper with a couple instructions might have helped,lol. Both pieces are Accufab. Thanks.

Sorry for sounding stupid but haven't gotten to "play" yet with tuner. Downloaded custom tune from Brenspeed with SCT tuner ....can I adjust idle with tuner?

First try disconnecting the battery for at least 5 minutes. It should have been done after you installed the new TB and plenum. It resets the cars KAM (Keep Alive Memory) and basically makes the computer relearn values in the air trim or something like that since you now have a new TB and plenum which causes more airflow.

Try that first

yea try unhooking the battery, but yes you can tune the idle with the tuner...
