Hey everyone, I've got an annoying misfire that I can't figure out. My car has a 57trim turbo, 550's, lex afm, and Safc-2. I was out trying to tune the car today and I get a misfire around 3k-3400 rpm then it clears up and is gone. If I bring the rpms up to 3.5k and accelerate it will still misfire as the boost is coming up. I have concluded that the misfire is more related to boost coming on rather than rpm. I put new ngk 3330's in gapped to .028 and it does the same thing. I am not sure where to go from here. Any help is greatly appreciated.
