HELP: s14 sr20det stalling

[bK_S14]

New S14 SR20det swap. Everything seems fine. No idling issues. TPS set accordingly.

Only issue is the car will stall if i clutch in or i'm in neutral after a little boost.

My throttle body was leaking coolant, so I bypassed it. Will this cause the stalling?

Also, tested the BOV (not recirc) by plugging the vacuum line and driving it. It still stalls.

Any advice is greatly appreciated!

Thanks!

After searching and reading a lot of different threads, I think it is a vacuum leak. Can someone please confirm?

Vacuum Configuration:
Currently I have all the vacuum lines running to the TB.
1. BOV to TB
2. FPR TB
3. Coldpipe to TB
4. Wastegate to TB <<<<---- Is this the problem? Will putting a nipple in the hotpipe and having the vacuum line going to the hotpipe solve things?
