Sorry Speed Racer, the NHSTA recently forced Autel to release a Software Optimizer updates across the board to remove the ability to raise the speed limiter and every failed attempt to retry reportedly  drops the vehicle speed limiter another 5mph until it defaults to European Union governed limit for delivery vehicles of  128.74752kph :-(  

  I was always tired of some BMWs getting the best of my Mustang GT so every J@gOff Beemer owner that comes in my shop comes leaves a Holy Terror until they hit 80mph and then the DME puts the banana in their tailpipes. Unfortunately the BMW guys are doing it to the Chevy  guys , and Ford guys are doing it to the Ferrari guys. Sooner or later the left lane is going to be safer place for Grandma to be in her mini van. :-)) Baaaahaha
