So many threads detailing issues and 9/10 cases it's probably due to AM stuff. Not that I'm against it, but If I had a dollar for every problem thread that mentions, "...I have a CIA...", I'd be able to buy my own!

Conspiracy!! :P

OP: Have you talked with Visconti about your issues? Done any datalogging?

I didnt mean to create an issue here. I was out of the country almost two weeks and did not have internet access. Anyway, It was my mistake that I did not give enough information at the beginning. Before the Tune, my car was completely stock except K&N filter.I used 95RON E10 which is regular gas here. It is very difficult to find 100% gasoline in my country. Mileage was around 14,000mile before tune. About a month ago, I got visconti E20 tune. Then, I replaced my mid pipe. About a week after, I got Cel and found out about spark plug issue.

Sorry to bother you guys. I just want to share what I found.

John mentioned that the damage may be caused by gasoline quality. I have done some dataloging. They looked okay excpet oil temp is quite high, 250F, when I drove hard on the high way.

After I have popping sound, i took the plug off to check and found out about the plug gap.

I think C1201 is just a general "hey something is wrong" DTC code which pulls power.

In my case, It started from P0301 and other codes came later when I was driving to the shop. I think P0301 came up because the spark plug damage.

hi Peachch, same issue today on the track engine and traction on, just past 30 000 km ( 14000 mile) running a trubo and 95 on the pump. Did the plug replacemet fix your problem and what plug did you use.

Im not an expert in tuning, but you might take a look at the 2015 subaru wrx to see which spark plugs they are using since they are also using the FA20.
