2016 Mk7 GTI DSG 64k miles. Recently I decided to tune my car so went and got a Cobb AP, putting their OTS stage 1 tune on and all. Problem starts immediately with WOT, as soon as rpm reaches above 5k the car would sound like a Subaru, throws EPC light and runs like crap until you turn it off and on again with P0304 Cyl4 Misfire,P130A Hide cylinder. Cleared codes and Flashed back to stock map, car runs fine even in full throttle. Thought it might be because of the tune so I went ahead and got a base tune from EQT, along with new rs3 coils and rs7 plugs gapped at .025 just to be on the safe side. However the same problem came back in exactly the same in WOT situation and same codes. Anyone experienced these problems and what would be the solution? I got some theory such as carbon buildup, bad PCV, or plugs need to be gapped more... I'm really lost here.
