    What's the rest of the combo? Cam? Intake? Headers? It's kind of important stuff to know.

    no wideband and running open loop? Turn your closed loop on to see where your trims are at. Log dynamic and vve airflows too.

    You don't have to make multiple threads for the same issue. All three of your threads are the same problem. Idle drops, stalls, etc. It all revolves around dialing in your VVE and MAF table. Put it back in closed loop and use your trims to dial them both in.
