Disable the code/delete from the rom. With aggressive cam and 1000cc you will always get p0300.

Check your tune. White plugs = Lean. I have the same issue as you, and my plugs look the same. Like others have said, BPR8ES gapped .022-.024 (stock coils) and you should be fine. However, you may find out (like I did) that you just don't have enough fuel, and that "misfire" that you think is spark blowout is really detonation at 6k.

What turbo and how much boost are you running?
