Has anyone had this problem on a Vortech S/C 05' G35 high-rev coupe? I've scene this happen on a turbo SE-R but never had a follow up on what caused it. The e-manage ultimate was working fine on the dyno untill it started missing. Number five coil was hot and had bulged out the plastic casing. No problems with communication to the lap top either. Up to that point, tuning was going fine. The wireing for the e-manage has been check several times as well.
