Running poorly after turbo upgrade and fmic Install

[jkasza87]

Hey everyone new the forum and turbocoupes. I just installed my gnari turbo kit, egr delete with block off plate and egr solenoid disconnected, stinger fmic with dual piston bov. My issues are surging idle cold and hot, stalling under load and overall poor performance. I have good fuel pressure and tested my regulator(both stock) idles fine at first but once you give it any sort of throttle it acts up. Wondering if it's the bov or vam any input would be great thanks

Sounds like a vacuum leak. You can pressure test it like it shows in this post in the FAQ:

You can also use the block off plug that came with the BOV to test/delete the BOV.
