Just wondering if anyone else is seeing low power numbers on the dyno for 2013 GT? In a previous post I had shared that with CAI, X pipe and custom tune I was only putting down high 360s RWHP. Most cars this tuner has done with same setup are in the low 400s. The tuner seemed to think I had a bad or weak firmware file from Ford. I spoke with Ford and they show no issues or upgraded files for the car. My tuner had a ford tech plug into the car and it showed no issues. He has seen this in more than one car now, mine was the first. Mine is auto, but has also seen in manual cars. He has spoken with other tuners around the country he knows and says they are seeing similar issues in he 13s. One theory is that due to the high number of cylinder 8 issues in the 11 and 12s, that Ford has done some things in the background of the firmware file to block some of the tuning parameters. The dyno is a dyno jet. Has anyone else experienced or heard anything along these lines?
