RPM Drop After Revs

[DSM Chase]

I have a pretty big thread on this in the newbie section but im not really getting any help with my logs im providing so here we go..

Anytime I rev my car upwards of 5K and start to hit my 2 step or anti lag as soon as i let of the gas the rpms just fall to 0 and she shuts off, Sometimes it will bobble at like 200Rpms and shoot back to 1K (link idle Setting). Also does it if you are driving down the road and push the clutch in and hold it, it usually will do the same thing.

Could be some sort of surge did you do the basic boost leak test, before all those parts?

Car has no boost leaks...

I'm experiencing the same exact problem. If I decel in gear and clutch in at ~2000rpms it will catch ok. I was thinking it was related to my flywheel. Do you have a lightened flywheel? (edit: just read in your post that you do. hmm...)

I am also having the same problem. I also have no boost leaks, but i do have a lightweight flywheel. I am not sure if this has something to do with it.

I'm thinking the biss needs adjustment. I'll verify, adjust and report back...

UPDATE: just confirmed that my biss definitely needs adjustment. ISCposition reads 85 at idle...

Adjusting the biss fixed the problem

OK here's a newbie question, what do you mean by "biss"?

Im having the exact same problem: no boost leaks, replaced IAC, EGR, and have a lightweight flywheel. this might be the answer Im looking for.
Edit: Google answered that for me. So Basically All I need to do is check the o-ring and set the idle, and I should be good?

BISS screw is located on the throttle body

also do you run SD or an MAF?

I am still having the problem. No boost leaks. I am running stock maf. It seems to only happen when the bov opens. If i go real easy to 4k the rpms will drop fine, but as soon as i give it enough for the bov to open, it dies. And yes my bov is recirculated. My tps reads 0 and i can hardly ever get it to read 1. My iac steps are at 30 at idle.
