So my 16 just started pulling all the timing under boost. It drops to -4 to -6 degrees but its not throwing a code for it. Feels like a misfire but there is no miss. Has anyone else had this issue?

Need significantly more information. Laziest way to get help would be to post up some datalogs using datazap. It would also be helpful to have a full modification list.

Could be as simple as something clanging under the hood making the car thinking there is knock, or could be something catastrophic... No way to know without more info.
