Do you have ISTA+ ? Or carly? This may help...

Have you checked and cleaned the MAFs and air intake boots?

My last suggestion is possibly gapping to 0.020. Its kind of alot of work, so Id do that last. Maybe keep talking with your tuner about it. Im gapped at 0.020 with ngk one step colder and it works for me. Tuned also, etc.. with catless dp.
