Ok civicx, I need your help. I am the proud owner of a 16 civic coupe 1.5T. It has the injen short ram intake, an exhaust unbolted at the downpipe, a tourge solutions blow off valve adapter plate and a Ktuner 1.2. After installing the plate i noticed a gas smell coming from the exhaust and my check engine light went on. I reved in my garage for a bit to see if i could find anything wrong and when dropping the RPM the engine sputters and dips below 600. I fired up the ktuner software and it showed a knock and a misfire on cylinder 3. Took out the sparks and they were matte black all over. The intake filter looked like it had some sort of residue on it. My job depends on my car, can anyone tell me what might be going on?

take your blow off valve plate out, your car is running rich when you let off the throttle after boosting since it's expecting the boosted air to return to the engine and it's not getting it. The sound is nice but not worth the loss of engine reliability.
