HELP!! Engine cutting out

[STcub]

So in an instant my car started acting up. In 3rd and 4th under 75% or higher acceleration the engine starts to sputter and cut out. Its still making boost, no check engine light or codes being thrown, nothing leaking. If i drive it conservative you can tell there is an issue. I did get a data log of it as well. I will try and post that up. Any help is appreciated!

Check for codes. There are some that register in diagnostic but do not lock until a few occurrences. To hazard a guess I would start looking at the spark plugs and coil packs. Could be loose. Bad gas could be a problem or a low octane gas when using a high octane tune

I checked the codes and nothing comes up on my accesport. I'm e30 tuned and get gas at the same station so i dont think it gas. Going to check the plugs soon.
