I have a velocity element manifold and a radium fuel rail so i dont have vacuum on the rail any more. Originally the pvc was replaced with a radium swivel fitting and piped Yed into my catch then into back intake. No mafs, all on map via link.
We tried everything on idle. 1100 rpm, raise warmup fuel trim, reduce fuel trim, change idle timing, replace iacv with genuine new one... all of that did not work. There was constant surging and buckling on idle.
Pissed me off so bad. I was like f...it and put a check valve after the Y before the catch. BAM idle at 950 rpm, steady. I am on hks step3 264/272 cams with reduced overlap. 0 changes to anything except added PCV.

I used -10 barb cause my vacuum lines are pushlock and pretty big
