I was putting in a new O-ring for the IAC and noticed a vacuum line going to nothing. It's the vacuum hose on the top of the Wastegate Control solenoid, it's still attached to the Wastegate Control Solenoid but when I follow the vacuum hose it's disconnected with a plastic nozzle on the end of it.
The Stealth 316 free boost mod says its the, to intake hose by rear turbo.
I tried looking around but unsure where it's located at, can anyone help me out?
A: There should be a vacuum routing diagram on the underside of your hood.
B: If that's a Hallman boost controller I'm looking at in the first pic, you don't need to worry about the vacuum lines going to the wastegate solenoid or the free boost mod.
There should be a nipple on the back side of the rear turbo intake hose, facing the firewall.
It stays 1500 when warm. I'll drive it around and see if it re-learns if not I might have vacuum or boost leak somewhere.
Edit: Driving it around didn't do much.. Now I know why when I turn on the AC the idle drops instead of raises.
I turned the bolt on the Dashpot lower so it dropped the idle to around normal. I forgot that the last few times I messed with the Dashpot adjustment and had the bolt backed out a lot of turns which made my idle higher.
I put the Dashpot back to the original spot it was at..well maybe I backed it out a little bit for a little bit higher idle Now the warm idle is 800-900.

I don't know what you have done to your TB, but the dashpot has absolutely nothing to do with idle LOL.
