2011 C6 Base 6.2 Procharged Idle Surge

[kevinr43]

I have a 2011 C6 Base 6.2 pro charged (ECS1500SL)
Long Tubes
X-Pipe
stock cam to my knowledge
3 bar Bosch map sensor
speed density tune
I don't know what injectors it has in it

I'm having issues with it idling properly, it surges anywhere from 1,000 rpm to 200 rpm and sometimes dies, i can tap the gas pedal and it levels out the idle and idles fine for about 10 seconds and goes back to surging. While driving the car it will also sometimes buck and or cutout. Ive checked for vacuum leaks and so far haven't come across any, I'm thinking it can possibly be an issue with the tune.

It seems to be a common problem with either the kit or these cars from what I've read. I'm just looking to get a bit better insight. I'm new to the game so hoping to get some information that can help.

Tune and log or there isn't much anyone can add.

Figure out the injectors or get known good ones with good data. If the ecm can't control fuel then it can't control anything Also I'm dialing in the ITT on one right now where they told the owner to put a breather on the oil fill cap. Apparently comes with the kits? Crankcase ventilation system needs to be right otherwise you're just fighting more problems with the big vacuum leak.
