From what I have read these are egr and overboost. I have a stock motor with a gfb bov and a tbe. Sometimes not all the time, I hit what I believe is a fuel cut at 5k under boost. What could be causing my problem and what should I do to fix it? I just got the car so I am fairly new to tuning. I have heard I should get a tactrix cable along with their software to tune? I am also near some shops here in the bay such as FFTEC and GST motorsports. Could they tune my car and possibly fix my problem rather than me buying the cable? Sorry for the long post.

 

Taking your car to a tuner is a great idea. They will be able to tell you what is going on ANC more than likely.
