I went thru the same thing in May. When the engine was under full load with boost 1.1 to 1.2 bar, the car was misfiring really bad. This happened at the top of 3rd and 4th, 5th & 6th. My car had stock plugs installed . All of the research I did pointed to the plugs being gapped too large. The increased boost pressure actually blows out the spark causing a misfire. The stock plugs are gapped at 0.06"±0.008" from the factory. Under direction from friends and tuner, I changed my plugs to a Denso 3245 (PK20PR-P8) Gapped at 0.028". I also changed all the coil packs to 997's at the same time. The car has run perfect since. It makes great power without any hesitation. I would recommend this to everyone!
