2G idle issue

[just2asian]

I know this has probably been asked thousands of times, but if it's the case. I just did a Big t28 turbo swap with 650 cc injectors and 190 pump, but now if I get off the throttle weather it be light throttle or heavy my car's rpms seem to drive below the target idle and almost stall. Sometimes its worst, sometimes it's ok and doesn't dive low. Could it be a vacumm leak somewhere? Could it be an issue with the injectors or possible fuel pump issue? Any input would be lovely. Thanks.

Are you recirculating your bov?

What are you using to tune with? Did you retune after your install?

Hmmm, mine seems to do that too on and off randomly. I'll drop it into N and the RPM's will get real low and almost stall like you said.
Do you have any boost/ vacuum leaks? That could be a culprit.
Also, I'm not sure if this could be it, but my MAP sensor is pretty much dead, so that could be it too, just a guess.

I'm using DSMlink to tune, all the settings for fuel have been made. I'm gonna do a boost leak test sometime this week.
