Hanging/high idle manual tranny auto computer

[shr3dd3r 09]

Any idea who can help tune this thing how it needs to be tuned? Driving this thing around town is an interesting ordeal with it idling so fast...

Surely someone out there knows a tuner who can help me. SCT tech support sucks. They have yet to call me back.

I'm sure that I'm driving you nuts, but set the idle with the throttle body screw.
The IAC will never be able to make the truck idle any lower, as all it does is allow air to bypass the throttle blade.

I have already tried. The computer does what it wants to regardless. I can remove the IAC all together and seal the holes completely, AND back the throttle screw all the way out so that the only air that gets in is through the tiny hole in the throttle blade. It will STILL idle at 1500 after it warms up. And no vacuum leaks.

I'm taking it to another SCT dealer outside of Nashville on Wednesday. The guy there said he has dealt with auto to manual swaps and is confident he can help me out. I'll be leaving it with him for a few days.
