Have you checked your plugs?coilpack? Maybe bad fuel?

I don't think you guys are understanding or not reading everything I typed. I said the car was misfiring due to a bad coil and DME did not throw a code on the epic tune, but the car was not running right.
Flashed back to stock and a misfire code popped up right away, moved when swapped coils. Coils were replaced and engine is running great, but there is now a lack of confidence in the tune if knock is being suppressed. Car ran for years without issue on the tune, the problem is when there is a issue if a tune is suppressing knock, the DME wont throw a code and it could be harmful to the engine.
