As I have stated, it is okay/normal for an increase in cackle noise. The increased ICP is what this results from. What I mean by my statements above is that it is not normal for a drastic increase in noise. Videos are hard decipher noise from. If you have been using the tunes successfully for some time, there should be no problem.
Drastic increases in noise can come from fuel issues as well, such as the case of the OP. Also, worn out poppets in the injectors can cause excessive noise as well.
