So I hope I can get some insight.
I just rebuilt my lt-1 with stock internals.
Idles amazing but when revved the idle drops a few hundred rpm before it revs.
I do not have any vaccum leaks.
It's speed density.
All sensors are connected.
Thank you

You need to get a real time scanner on it and see what's going on.
Mine was doing this with a bad TPS.
Thank you both for replying.
Turned out to be a short in the wire from the PCM to the iac and a bad tps (no voltage change with position movement ) even though I just replaced it haha
