hey guys well i was on dyno tuning the car and while I was flashing the computer turned off. It says that the PCm had no program so I did a full fash, I can read , write to the PCM but when I drive the car it knocks constantly even at low rpm. I put the stock tune back on and I am still having the same issues, I am getting codes p0355, p0352, p0351, p0354, p0353, p0357, p0358, p0356

could this be coincidence or is it something with the car.

Is it safe to say that my PCM is ok ?
