2G Poor idle when clutch pushed in

[Turboed_talon_tsi]

I installed a new fmic and blow off valve on my project car and everything is fine expected for when the car warms up. When I push my clutch in and start to roll my rpm’s drop down to 200 and sometimes stalls out. I have tried adjusting my bov but that hasn’t been working.the bov is recirculating. Any solutions? Thanks

It's the job of the ECU with support of the IPS and IAC to maintain the engine speed. Other factors like lightweight flywheels and, sad to say, crankwalk can cause additional problems that the normal ECU software can't address.

I'd start with the "easy" stuff and make sure your normal maintenance items are up to date, that the IAC works and that the IPS is adjusted properly. Eliminate any vacuum leaks and then if you're still having issues have someone check your crank endplay.
