So I've noticed my car recently after like 4k rpms under wot has a boost issue, ill leave a link to the video, the boost fluctuates from like 17 to 13 back and forth a lot. Doesn't seem good. Anyone have any ideas?

My car does this too. I thought it may be a boost leak because I have a mountune B7 kit which comes with a 91 octane tune. When I put the stock tune back on I noticed it dosent do it. So im kinda lost.

If the car is not dialed in with custom tuning, then this is very likely to happen. Let me know if you need help with that.

Do you do custom tuning? And how does it work. I am still kind of new when it comes to tunes. Thank u
