I wasn't saying the turbos were the cause of my misfire, my turbos are excellent!!! I have a front 02 sensor that went to crap, which is giving me a 2C9D (Lambda probe heating in front of catalytic converter 2, input signal) which is making me run lean. My afr2 is reading 20.0 which is kicking me to map 4. I have the ngk 5992's gapped at .22. Once i get this 02 sensor il send some logs!


FBO N54, DOC 6466 Boostbox MHD, EOS intake manifold w/PI, Fuel-it stage 3, Xhp stage3, Zebra Cake coils, etc etc.....
