If you own a first-gen Coyote automatic, you might have been jealous of the high-revving antics of those manual-transmission cars. Well, you can now end that envy thanks to the industrious crew at HP Tuners. They have cracked the code to allow 2011-2014 Mustang GT automatics to rev all the way past 8,000 rpm.
“The 11-14 Coyotes use a different PCM,†Eric Brooks, Ford Calibration/Development specialist at HP Tuners, said. “The 2015 PCM is quite a bit more powerful and from the factory do not have some of the limits that the Copperhead PCM has.â€
While the newer PCM is powerful it has its own tuning challenges. When it comes to the Copperhead unit that controls the earlier Coyotes, there was an easy fix to make the manual-transmission cars rev like their RoadRunner and Voodoo cousins.
