I hope this helps someone, at first we had misfire issues, I thought it was the b8ef plugs, so we swapped in a set of br7ef and gapped em down to .020", first couple of runs were clean but started having sputtering and ignition breakup issues. I noticed that the ignition wires were all in contact (wrapped in heat wrap and some zipties due to relocated coil packs), so we got rid of that and made sure there was no contact. Issue was immediately gone. My assumption is that there was some crossfiring or EMF issues, maybe need some shielding ? Anyways here's some pics
