I have every bolt on including custom longtubes, supersix powerpack comp .507 220/224 114ls cam, 36oo stall converter, pcm programming, ls1 injectors, 3.73 lsd and more. i have autotap and im getting a p0300 and p0302 cylinder 2 misfire, i replaced plugs wires, coilpacks, fuel filter etc. my car doesnt sound like its missing, i do have to get it on the dyno to get the air fuel tuned so my et is where it should be, i dont know how to get rid of this misfire, i understand that the p0300 could be due to the large cam but if it was just the cam causing this then it wouldnt be cylinder specific, by saying cylinder 2 isfire most of teh time.
