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.
